When is A+XB[[X]] Noetherian?

Abstract: Let A ⊆ B be an extension of commutative rings with identity, X an analytic indeterminate over B, andthe subring of the formal power series ring B[[X]], consisting of the series with constant terms in A. In this Note we study when the ring R is Noetherian. We prove that R is Noetherian if and only if A is Noetherian and B is a finitely generated A-module.

“…Note that S. Hizem and A. Benhissi [12] have already given a characterization of the Noetherianity of the power series rings of the form A C XBOEOEX . We preserve the notation of As a consequence of the previous proposition, we can characterize when rings of the form A C XBOEX and A C XBOEOEX are Noetherian.…”

“…In [10,[12][13][14], the authors characterized when composite rings R C XDOEOEX and R C XDOEX are Noetherian rings, S-Noetherian rings, or satisfy the ascending chain condition on principal ideals. It was shown that RCXDOEOEX (resp., R C XDOEX ) is a Noetherian ring if and only if R is a Noetherian ring and D is a finitely generated R-module …”
