Question

can any one guide me about the best notes for group theory....that are helpful for in clearing my concepts and provides me extra knowledge...

Answer 1

Group theory? To prove something is a group? (Abstract Algebra)

Answer 2

yes i thing it might be a part of abstract algebra...but i m studying this subject by the name of group
theory

Answer 3

To show set G is a group under operation * (star)
(1) Associative
(2) Identity
(3) Inverse

Further more, if G is communitive ab=ba, then the group is Abelian.

Answer 4

no i want to get the notes of group theory(abstract algebra in ur words) if u know the best notes for this subject,send me link if u can..... your ans is a basic concept and i m already familiar with it...

Answer 5

Sets are the collections of objects. The difference between sets and groups is whether it is closed under some operation *(star). For example, integers Z is a group under addition(+).

Answer 6

You can also think is this way: group is a self-complete operation set. Like Z, 1+1=2 in Z. 2+3=5 in Z.

Answer 7

and that operation is called binary operation - a function that assigns each ordered pair of elements in group an element of group. or f(a,b)=c which a, b, c are all in the group.
