Web30 Nor Muhainiah Mohd Ali, Deborah Lim Shin Fei, Nor Haniza Sarmin, Shaharuddin Salleh (3) Inverses. For each element a in G, there is an element b in G (called the inverse of a) such that ab = ba = e. A group is Abelian if the group has the property of ab = ba for every pair of elements a and b.In short, this means that the group is commutative.

WebTry to figure out what conditions this imposes on your choice of f ( 1). See user26857's answer if you are stuck. Note that the answer will depend on whether you require that a ring homomorphism f: R → S must preserve multiplicative identities, i.e. f ( 1 R) = 1 S.
