WebIn ring theory, a branch of abstract algebra, a ring homomorphism is a structure-preserving function between two rings.More explicitly, if R and S are rings, then a ring homomorphism is a function f : R → S such that f is:. addition preserving: (+) = + for all a and b in R,multiplication preserving: = () for all a and b in R,and unit (multiplicative identity) … WebShortcut method for finding homomorphism from Zn to ZmNumber of homomorphism from Zn to Zm = gcd(m, n)Number one one and onto homomorphism from Zn to Zm early in his career david bowie started as a
