    • Cohen-macaulayness of tangent cones 

      Arslan F. (2000)
      We give a criterion for checking the Cohen-Macaulayness of the tangent cone of a monomial curve by using the Gröbner basis. For a family of monomial curves, we give the full description of the defining ideal of the curve ...
    • Complete intersection monomial curves and the Cohen—Macaulayness of their tangent cones 

      Katsabekis, Anargyros (World Scientific Publishing, 2019)
      Let C(n) be a complete intersection monomial curve in the 4-dimensional affine space. In this paper we study the complete intersection property of the monomial curve C(n + wv), where w > 0 is an integer and v ∈ ℕ4. In ...
    • On pseudo symmetric monomial curves 

      Şahin, M.; Şahin, N. (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 ...
    • On the Cohen–Macaulayness of tangent cones of monomial curves in A 4 (K) 

      Arslan, F.; Katsabekis, Anargyros; Nalbandıyan, M. (TÜBİTAK, 2019-05)
      In this paper we give necessary and sufficient conditions for the Cohen–Macaulayness of the tangent cone of a monomial curve in 4-dimensional affine space. We particularly study the case where C is a Gorenstein noncomplete ...
