Upcoming Seminars

  1. Fellowship of the Ring, National Seminar: Differential powers of ideals

    Location: MSRI: Online/Virtual
    Speakers: Luis Núñez-Betancourt (Center of Investigations in Mathematics (CIMAT))

    To attend this seminar, you must register in advance, by clicking HERE.

    In this talk we will discuss a class of powers that was recently defined using differential operators. In the first part, we
    will review the basics for rings of differential operators. Then, wewill discuss the definition of differential powers and its connections with symbolic powers. The second part of the talk will focus on the use of these powers to study singularities. The original results are part of three projects with: Dao, De Stefani, Grifo, Huneke (2018); Brenner, Jeffries (2019); and Duarte (2020).

  1. Seminar Fellowship of the Ring, National Seminar: Commutative Algebra with S_n-invariant monomial ideals

    To attend this seminar, you must register in advance, by clicking HERE.

    Consider a polynomial ring in n variables, together with the action of the symmetric group by coordinate permutations. In my talk I will describe many familiar notions in Commutative Algebra in the context of monomial ideals that are preserved by the action of the symmetric group. These include Castelnuovo-Mumford regularity, projective dimension, saturation, symbolic powers, or the Cohen-Macaulay property. My goal is to explain how changing focus from minimal resolutions to Ext modules can lead to a simplified picture of the homological algebra, and to provide concrete combinatorial recipes to determine the relevant homological invariants.
