Initially regular sequences and depths of ideals
Louiza Fouli, Huy Tai Ha, Susan Morey
For an arbitrary ideal in a polynomial ring we define the notion of initially regular sequences on . These sequences share properties with regular sequences. In partic…

Depth and regularity of monomial ideals via polarization and combinatorial optimization
Jose Martínez-Bernal, Susan Morey, Rafael H. Villarreal +1
In this paper we use polarization to study the behavior of the depth and regularity of a monomial ideal , locally at a variable , when we lower the degree of all the highes…
