4-generated pseudo symmetric monomial curves with not Cohen–Macaulay tangent cones
(TUBITAK, 2020)In this article, standard bases of some toric ideals associated to 4-generated pseudo symmetric semigroups with not Cohen-Macaulay tangent cones at the origin are computed. As the tangent cones are not Cohen-Macaulay, ... -
On pseudo symmetric monomial curves
(Taylor & Francis, 2017-12-15)We study monomial curves, toric ideals and monomial algebras associated to 4-generated pseudo symmetric numerical semigroups. Namely, we determine indispensable binomials of these toric ideals, give a characterization ...
