Field Axioms are assumed truths regarding a collection of items in a field. Let a, b, c be elements of a field F. Then: Commutativity: a+b=b+a and a*b=b*a Associativity: (a+b)…+c=a+(b+c) and (a*b)*c = a*(b*c) Distributivity: a*(b+c)=a*b+b*c Existence of Neutral Elements: There exists a zero element 0 and identify element i, such that, a+0=a a*i=a Existence of Inverses: There is an element -a such that, a+(-a)=0 for each a unequal to the zero element, there exists an a' such that a*a'=1 (MORE)
There are two types of mathematical axioms: logical and non-logical. Logical axioms are the "self-evident," unprovable, mathematical statements which are held to be univers…ally true across all disciplines of math. The axiomatic system known as ZFC has great examples of logical axioms. I added a related link about ZFC if you'd like to learn more. Non-logical axioms, on the other hand, are the axioms that are specific to a particular branch of mathematics, like arithmetic, propositional calculus, and group theory. I added links to those as well. (MORE)
4. Functional dependency In relational database theory, a functional dependency is a constraint between two sets of attributes in a relation from a database. Give…n a relation R , a set of attributes X in R is said to functionally determine another set of attributes Y , also in R , (written X â Y ) if, and only if, each X value is associated with precisely one Y value; R is then said to satisfy the functional dependency X â Y . Equivalently, the projection is a function , i.e. Y is a function of X .   In simple words, if the values for the X attributes are known (say they are x ), then the values for the Y attributes corresponding to x can be determined by looking them up in any tuple of R containing x . Customarily X is called the determinant set and Y the dependent set. A functional dependency FD: X â Y is called trivial if Y is a subset of X . The determination of functional dependencies is an important part of designing databases in the relational model , and in database normalization and denormalization . A simple application of functional dependencies is Heath's theorem ; it says that a relation R over an attribute set U and satisfying a functional dependency X â Y can be safely split in two relations having the lossless-join decomposition property, namely into where Z = U â XY are the rest of the attributes. ( Unions of attribute sets are customarily denoted by mere juxtapositions in database theory.) An important notion in this context is a candidate key , defined as a minimal set of attributes that functionally determine all of the attributes in a relation. The functional dependencies, along with the attribute domains , are selected so as to generate constraints that would exclude as much data inappropriate to the user domain from the system as possible. A notion of logical implication is defined for functional dependencies in the following way: a set of functional dependencies logically implies another set of dependencies , if any relation R satisfying all dependencies from also satisfies all dependencies from ; this is usually written . The notion of logical implication for functional dependencies admits a sound and complete finite axiomatization , known as Armstrong's axioms . Properties and axiomatization of functional dependencies Given that X , Y , and Z are sets of attributes in a relation R , one can derive several properties of functional dependencies. Among the most important are the following, usually called Armstrong's axioms :  .
Reflexivity : If Y is a subset of X , then X â Y .
Augmentation : If X â Y , then XZ â YZ .
Transitivity : If X â Y and Y â Z , then X â Z "Reflexivity" can be weakened to just , i.e. it is an actual axiom , where the other two are proper inference rules , more precisely giving rise to the following rules of syntactic consequence:  . These three rules are a sound and complete axiomatization of functional dependencies. This axiomatization is sometimes described as finite because the number of inference rules is finite,  with the caveat that the axiom and rules of inference are all schemata , meaning that the X , Y and Z range over all ground terms (attribute sets).  From these rules, we can derive these secondary rules:  .
Union : If X â Y and X â Z , then X â YZ .
Decomposition : If X â YZ , then X â Y and X â Z .
Pseudotransitivity : If X â Y and WY â Z , then WX â Z The union and decomposition rules can be combined in a logical equivalence stating that X â YZ , holds iff X â Y and X â Z . This is sometimes called the splitting/combining rule.  Another rule that is sometimes handy is:  .
Composition : If X â Y and Z â W , then XZ â YW Equivalent sets of functional dependencies are called covers of each other. Every set of functional dependencies has a canonical cover . (MORE)

Say there's a relation ~ between the two objects a and b such that a ~ b . We call ~ an equivalence relation if: i) a ~ a . ii) If a ~ b . then b ~ a . … iii) If a ~ b and b ~ c , then a ~ c . Where c is another object. The three properties above are called the reflexive , symmetric , and transitive properties. Were those three properties all that was needed to define the equality relation, we could safely call them axioms. However, one more property is needed first. To show you why, I'll give an example. Consider the relation, "is parallel to," represented by ||. We'll check the properties above to see if || is an equivalence relation. i) a || a . Believe it or not, whether this statement is true is an ongoing debate. Many people feel that the parallel relation isn't defined for just one line, because it's a comparison. Well, if that were true, then you would have to say the same thing for every binary equivalence relation; e.g., a triangle couldn't be similar to itself, or, even more preposterously, the statement a = a would have to be tossed out the window too. But, just to be formal, we'll use the following definition for parallel lines: Two lines are not parallel if they have exactly one point in common; otherwise they are parallel. So, with that definition in hand, i) holds for ||. ii) If a || b , then b || a . True. iii) If a || b and b || c , then a || c . True. Thus, the relation || is an equivalence relation, but two parallel lines certainly don't have to be equal! So, we need an additional property to describe an equality relation: iv) If a ~ b and b ~ a , then a = b . Let's check iv) and see if this works for our relation ||: If a || b and b || a , then a = b . False. But, does it hold for the equality relation? If a = b and b = a then a = b . True. This is what's known as the antisymmetric property, and is what distinguishes equality from equivalence. But wait, we have a problem. We used the relation = in one of our "axioms" of equality. That doesn't work, because equality wasn't part of the signature of the formal language we're using here. By the way, the signature of the formal language that we are using is ~. So, any other non-logical symbol we use has to either be defined, or derived from axioms. Well, we have three possible ways out of this. We can either: 1) Figure out a way to axiomize the = relation through the use of the ~ relation. 2) Define the = relation. 3) Add = to our language's signature. Well, 1) is not possible without the use of sets, and since the existence of sets isn't part of our signature either, we'd have to define a set, or add it to our language. This isn't very hard to do, but I'm not going to bother, because the result is what we're going to obtain from 2) . Anyways, speaking of 2) , let's define =. For all predicates (also called properties ) P , and for all a and b , P ( a ) if and only if P ( b ) implies that a = b . In other words, for a to be equal to b , any property that either of them have must also be a property of the other. In this case, the term property means exactly what you think it means; e.g. red, even, tall, Hungarian, etc. So, the million dollar question is, by defining =, are our properties now officially axioms? For three of the properties, the answer is no. In fact, because we just defined =, we've turned properties ii) , iii) , and iv) from above into theorems , not axioms. Why? Because, property iv) still has that = relation in it, which we had to define. So, iv) is a true statement, but we had to use another statement to prove it. That's the definition of a theorem! And, since the qualifier for iv) 's truth was that a ~ b and b ~ a , we can now freely replace b with a in ii) , giving us "If a ~ a , then a ~ a ." Well, now ii) 's proven as well, but we had to use iv) to do it. Thus, both ii) and iv) are now theorems. Finally, iii) can be proven in a similar was as ii) was, so it, too, is a theorem. However, our definition of = only related a to b , it never related a to itself. Thus, we need to include i) , from above, as an axiom. Just for kicks, let's try plan 3) too. The idea here is to make = a part of our signature, which means now we don't need to define it. In fact, we can't define it if we put it in our signature; because by placing it there, we're assuming that it's understood without definition. Therefore, iv) must now be assumed to be true , because we have no means to prove it; that sounds like an axiom to me! However, just like before, we can prove both ii) and iii) through the use of iv) , so they get relegated back to the land of theorems and properties. Interestingly though, iv) makes no mention of reflexivity, and since our formal definition of = is gone, we have no way to prove i) . Once again, we have to assume that it's true. Thus i) is an axiom as well. So, to paraphrase our two separate situations: In order for the relation ~ to be considered an equality relation between the objects a and b , one axiom must be satisfied if we define =: 1) For all a , a ~ a , as well as three theorems : 1) If a ~ b , then b ~ a 2) If a ~ b and b ~ c , then a ~ c , where c is another object 3) For all a and b , if a ~ b and b ~ a , then a = b . Additionally , In order for the relation ~ to be considered an equality relation between the objects a and b , two axioms must be satisfied if we put = into our signature: 1) For all a , a ~ a 2) For all a and b , if a ~ b and b ~ a , then a = b , as well as two properties : 1) If a ~ b , then b ~ a 2) If a ~ b and b ~ c , then a ~ c , where c is another object. .
What the one right above did is include "=" into our formal language, but "=" is equality, so he actually came up with a fairly well axiom before he finishes with the circular looking one. His axiom: We say ~ is an equality relation means whenever x ~ y, for any condition P, P(x) iff P(y) The axiom is the bolded part. After discussion with my Math prof. this morning, that axiom becomes a properties follows from this more formal definition. It does not need to include any more things then what we already have for the formal language. We say ~ is an equality relation on a set A if (a set is something that satisfies the set axioms) For any element in A, a ~ a. If follows that P(a) is true and y ~ a, then P(y) is also true, vice versa. Because in this case, y has to be a for it to work. You might argue well the definition for an equivalence relation have this statement in it too, does that mean equivalence IS equality? No! It's the other way around, equality is equivalence. Equality is the most special case for any relation, say *, where a * a. Take an equivalence relation, say isomorphisms for instance (don't know what that word mean? Google or as it on this website), we know any linear transformation T is isomorphic to T, in particular this isomorphism IS equality. Of course it would be boring if isomorphism is JUST equality, so it's MORE. The other axioms in a definition of a relation are to differ THEM from equality, because equality is the most basic. Equality must always be assumed, it always exist, any other relation is built upon it. It is the most powerful relation, because ALL relations have it. (I mean all relations, say *, such that a * a for all a must at least be equality) (MORE)
No, not at all. The Incompleteness Theorem is more like, that there will always be things that can't be proven. Further, it is impossible to find a complete and consistent …set of axioms, meaning you can find an incomplete set of axioms, or an inconsistent set of axioms, but not both a complete and consistent set.
