Summary Of: Abelian group
The concept of an abelian group is one of the first concepts encountered in undergraduate... Since the group operation in an abelian group is commutative as well as associative... is an abelian group with respect to its addition operation... do not form an abelian group under multiplication because matrix multiplication is generally not commutative... this theorem guarantees that an abelian group splits as a direct sum of a torsion group and a free abelian group... thus turns into an abelian group in its own right... It turns out that an arbitrary finite abelian group is isomorphic to a direct sum of finite cyclic groups of prime power order... of a finite abelian group can be described directly in terms of these invariants... The same can be said for any abelian group of order 15... every abelian group of order 8 is isomorphic to either... Encyclodia Page On: Abelian group
