prove that d (x1,xn)<=d (x1,x2)+d (x2,x3)+.................+d (xn-1,xn)
Matter is defined as that which has mass and occupies space. There are procedures to measure both. Even if you can't measure the mass of an object directly (such as a gas), you can still determine it's mass by measuring the space it occupies. Pressure is one way to measure the mass of gas by the amount of space it occupies.
I don't think there is any energy associated with empty space.
One metric ton of feathers will have a much larger volume than a ton of steel ingots.
A solid is more compact.
well solids would be particuls all compact then liquads would be less compact and so on for gases... this usually occurs from van der walls forces breaking from heating and then there is just empty space between particles that are in a gas form
No.
A metric on a set is complete if every Cauchy sequence in the corresponding metric space they form converges to a point of the set in question. The metric space itself is called a complete metric space. See related links for more information.
Any closed bounded subset of a metric space is compact.
The question doesn't make sense, or alternatively it is true by definition. A Hilbert Space is a complete inner product space - complete in the metric induced by the norm defined by the inner product over the space. In other words an inner product space is a vector space with an inner product defined on it. An inner product then defines a norm on the space, and every norm on a space induces a metric. A Hilbert Space is thus also a complete metric space, simply where the metric is induced by the inner product.

large population and lack of space in the cities, the settlement is compact
8.5 feet, 7.5 feet for a compact space
No. Every infinite dimensional topological vector space is not locally compact. See the Wikipedia article on locally compact spaces.
I am also dying to know geometrical interpretation of semi-metric space . If anyone have idea please do infrom me as well
The Cadillac DTS is considered a full size luxury car. Most full size autos will not easily fit into a compact car parking space and the DTS is no exception. Chances are that the car would be too wide and/or too long to fit comfortably in a compact parking space.
