WebIn group theory, the result known as Lagrange's Theorem states that for a finite group G the order of any subgroup divides the order of G. However, group theory had not yet been … WebThe Fundamental Homomorphism Theorem The following result is one of the central results in group theory. Fundamental homomorphism theorem (FHT) If ˚: G !H is a homomorphism, then Im(˚) ˘=G=Ker(˚). The FHT says that every homomorphism can be decomposed into two steps: (i) quotient out by the kernel, and then (ii) relabel the nodes via ˚. G ...
