Affine semigroups of maximal projective dimension
Om Prakash Bhardwaj, Kriti Goel, Indranath Sengupta
We generalize the notion of symmetric semigroups, pseudo symmetric semigroups, and row factorization matrices for pseudo Frobenius elements of numerical semigroups to the case of s…

On Row-Factorization relations of certain numerical semigroups
Om Prakash Bhardwaj, Kriti Goel, Indranath Sengupta
Let be a numerical semigroup minimally generated by an almost arithmetic sequence. We give a description of a possible row-factorization $(\RF)$ matrix for each pseudo-Frobeniu…
