Projective Closure of Affine Monomial Curves II
Joydip Saha, Indranath Sengupta, Pranjal Srivastava
In this paper our aim is twofold. First, we introduce the notion of star gluing of numerical semigroups and show that arithmetically Cohen-Macaulay and Gorenstein properties of the…
ASL structures of some quadrics
Joydip Saha, Indranath Sengupta
Let be a field and , denote matrices such that, the entries of are either indeterminates over or and the entries of are indeterminates over which are…
Numerical Semigroups with unique Apéry expansions
Sudip Pandit, Joydip Saha, Indranath Sengupta
In this paper, we carry out a fairly comprehensive study of two special classes of numerical semigroups, one generated by the sequence of partial sums of an arithmetic progression…
Projective closures of affine monomial curves
Joydip Saha, Indranath Sengupta, Pranjal Srivastava
We study the projective closures of three important families of affine monomial curves in dimension , namely the Backelin curve, the Bresinsky curve and the Arslan curve, in ord…
