(Generalized) filter properties of the amalgamated algebra

Commutative Algebra 2024-11-21 v1

Abstract

Let RR and SS be commutative rings with unity, f:RSf:R\to S a ring homomorphism and JJ an ideal of SS. Then the subring RfJ:={(a,f(a)+j)aRR\bowtie^fJ:=\{(a,f(a)+j)\mid a\in R and jJ}j\in J\} of R×SR\times S is called the amalgamation of RR with SS along JJ with respect to ff. In this paper, we determine when RfJR\bowtie^fJ is a (generalized) filter ring.
