Olsavsky will use a prime ideal to create a multiplicative system M in the ring of integers Z . This allows him to create a quotient ring R_M . The quotient ring R_M contains an ideal A , which consists of the non-units of the quotient ring . He will use a particular example in Z to illustrate this . Any ring R in which the non-units form an ideal is called a local ring.The talk will be accessible to . undergraduates Categories Seminar Tags Seminar No
