On the projective dimension of tensor products of modules

Olgur Celikbas, Souvik Dey, Toshinori Kobayashi

In this paper, we consider finitely generated modules over commutative Noetherian rings whose tensor products have finite projective dimension. We construct examples of modules of…

Finite Birational extension with stable conductor

Souvik Dey

Let be a module finite birational extension of a -dimensional local Cohen--Macaulay ring . When is the conductor of in a stable ideal? If is also generically…

Some characterizations of local rings via reducing dimensions

Olgur Celikbas, Souvik Dey, Toshinori Kobayashi +1

In this paper we study homological dimensions of finitely generated modules over commutative Noetherian local rings, called reducing homological dimensions. We obtain new character…

Trace ideal and annihilator of Ext and Tor of regular fractional ideals, and some applications

Souvik Dey

Given a commutative Noetherian ring with total ring of fractions , and a finitely generated -submodule of , we prove an equality between trace ideal, and cer…

Ulrich split rings

Hailong Dao, Souvik Dey, Monalisa Dutta

A local Cohen--Macaulay ring is called Ulrich-split if any short exact sequence of Ulrich modules split. In this paper we initiate the study of Ulrich split rings. We prove several…

On a generalized Auslander-Reiten conjecture

Souvik Dey, Shinya Kumashiro, Parangama Sarkar

It is well-known that the generalized Auslander-Reiten condition (GARC) and the symmetric Auslander condition (SAC) are equivalent, and (GARC) implies that the Auslander-Reiten con…
