Degree and algebraic properties of lattice and matrix ideals
(2014-01-01)
Article
Accés obertWe study the degree of nonhomogeneous lattice ideals over arbitrary fields, and give formulas to compute the degree in terms of the torsion of certain factor groups of Z(s) and in terms of relative volumes of lattice ... -
Ideals of Herzog-Northcott type
(2011-01-19)
Article
Accés obertThis paper takes a new look at ideals generated by 2×2 minors of 2×3 matrices whose entries are powers of three elements not necessarily forming a regular sequence. A special case of this is the ideals determining monomial ... -
Noetherian rings of low global dimension and syzygetic prime ideals
(2021-02-01)
Article
Accés obertLet R be a Noetherian ring. We prove that R has global dimension at most two if, and only if, every prime ideal of R is of linear type. Similarly, we show that R has global dimension at most three if, and only if, every ... -
Prime ideals in three dimensional regular local rings
(Universitat Politècnica de Catalunya, 2020-07)
Projecte Final de Màster Oficial
Accés obertThe aim of this work is twofold. First we study a family of prime ideals, in the power series ring in three variables over a field, which need arbitrarily high number of generators. This family was introduced by T. T. Moh ...
