Amongst other things they independently invented calculus. Newton probably made the first discovery, but delayed publishing for many years. Leibniz also held off publishing for a long time, waiting, apparently for Newton to do it. Eventually Leibniz published anyway. They became bitter rivals.
Newton was outraged because he believed that Leibniz had stolen his ideas on calculus. Newton and Leibniz both independently developed calculus, but Newton felt that Leibniz had plagiarized his work. This led to a bitter dispute between the two mathematicians known as the "calculus priority dispute."
Gottfried Wilhelm Leibniz
both were the mathematician who develop the finite intgral method
As a scientist, he is mainly known for the general law of gravitation, and Newton's laws of movement. As a mathematician, he basically invented calculus (so did another mathematician, Leibniz, independently of Newton).
Not a theory, They discovered a branch of math called calculus.

No, Newton, an Englishman, and Leibniz, a German, were both accomplished mathematicians, who independently developed an early form of calculus.
Isaac Newton and Gottfried Wilhelm Leibniz
Both of them came up with the concept (semi-) independently; both were aware that the other was working on it and in fact they exchanged letters on the subject, but they approached it from different directions (Newton started with differentiation, Leibniz started with integration). Going by their private papers it appears that Newton was further along earlier than Leibniz, but Leibniz published a full description much earlier than Newton did.
Isaac Newton and Gottfried Leibniz.
Gottfried Wilhelm Leibniz
Isaac Newton and Gottfried Wilhelm Leibniz are credited with inventing calculus independently of each other around the same time. Each used his own notation. Calculus is more commonly associated with Newton than with Leibniz.
Yes, although Newton did contribute.
