a ring homomorphism f: a→b is finite. 環(huán)同態(tài)f:AB叫做有限型的。
So finding the minimal polynomial of a block circulant matrix is transformed into computing the reduced grobner basis of a kernel of a ring homomorphism 因此,將求域上塊循環(huán)矩陣的極小多項式轉(zhuǎn)化為求一個環(huán)同態(tài)的核的簡化gr (

In ring theory or abstract algebra, a ring homomorphism is a function between two rings which respects the operations of addition and multiplication.
