Multiplicities and Mixed Multiplicities of arbitrary Filtrations
Steven Dale Cutkosky, Parangama Sarkar
We develop a theory of multiplicities and mixed multiplicities of filtrations, extending the theory for filtrations of -primary ideals to arbitrary (not necessarily Noetherian)…
Frobenius Betti numbers and syzygies of finite length modules
Ian M. Aberbach, Parangama Sarkar
Let be a local (Noetherian) ring of dimension and a finite length -module with free resolution . De Stefani, Huneke, and Núñez-Betancourt ex…
Mixed Multiplicities of Filtrations
Steven Dale Cutkosky, Parangama Sarkar, Hema Srinivasan
In this paper we define and explore properties of mixed multiplicities of (not necessarily Noetherian) filtrations of -primary ideals in a Noetherian local ring , generaliz…
Multigraded regularity, reduction vectors and postulation vectors
Parangama Sarkar
We relate the set of complete reduction vectors of a -graded admissible filtration of ideals with the set of multigraded regularities of $G(\mathcal{F})…
Variations on the Grothendieck-Serre Formula for Hilbert functions and their applications
Shreedevi K. Masuti, Parangama Sarkar, J. K. Verma
In this expository paper we present proofs of Grothendieck-Serre Formula for multi-graded algebras and Rees algebras for admissible multi-graded filtrations. As applications, we de…
