Derivation module and its Poincaré series of the projective closure of certain affine curves
Joydip Saha, Indranath Sengupta, Pranjal Srivastava
Our aim in this paper is to compute the Poincaré series of the derivation module of the projective closure of certain affine monomial curves.
On the Associated Graded ring of Semigroup Algebras
Joydip Saha, Indranath Sengupta, Pranjal Srivastava
In this paper, we give the necessary and sufficient conditions for the Cohen-Macaulayness of the associated graded ring of a simplicial affine semigroups using Gröbner basis. We ge…
Numerical Semigroups with unique Apery expansions II
Joydip Saha, Gaurab Tripathi
In this paper, we carry out a fairly comprehensive study of special classes of numerical semigroups, and their tangent cones, generated by the sequence of partial sums of an arithm…
Unboundedness of the first and the last Betti numbers of Numerical Semigroups Generated by Concatenation
Ranjana Mehta, Joydip Saha, Indranath Sengupta
We show that the minimal number of generators and the Cohen-Macaulay type of a family of numerical semigroups generated by concatenation of arithmetic sequences is unbounded.
