Colloquium

The weekly colloquium features a talk by an invited speaker. Topics vary and include all areas of mathematics.

Unless otherwise noted, the colloquium takes place on Tuesdays, 14:00 in room 614, 6’th floor of the Science and Education Building. For further details, please contact the colloquium coordinator, Dr. Adam Dor-On.

Colloquium: Tuesday, May 24, 2022. Speaker: Uzi Vishne (Bar-Ilan). Title: “Inclusion-exclusion, partial representations of semigroups, and nonassociative polynomials”.

You are also welcome to join us on Zoom at: https://us02web.zoom.us/j/83337601824 Time: 14:00 Abstract: The dimension of the space of multilinear products of higher commutators is equal to the number of derangements, $[e^{-1}n!]$. Our search for a combinatorial explanation for this…

Colloquium: Tuesday, March 29, 2022. Speaker: Speaker: Christopher Voll (Bielefeld). Title: “Zeta functions of groups, rings, and modules”.

The zoom link for our meetings is:https://us02web.zoom.us/j/83337601824 Abstract: Zeta functions are ubiquitous in mathematics. In algebra and geometry, they often have an enumerative interpretation, prominent examples being the Dedekind zeta function of a number field and the (Weil) zeta function of…

Colloquium: Tuesday, March 8, 2022. Speaker: Jurij Volcic (University of Copenhagen). Title: “Determinantal zeros of noncommutative polynomials”.

The zoom link for our meetings is: https://us02web.zoom.us/j/83337601824 Time: 14:00 Abstract:  Hilbert’s Nullstellensatz on zero sets of polynomials is one of the most fundamental correspondences between algebra and geometry. In recent years, there has been an emerging interest in polynomial equations and…

Colloquium: Tuesday, February 22, 2022. Speaker: Shira Zerbib (Iowa State University). Title: “KKM-type theorems and their applications”.

Time: 14:00 Abstract: The KKM theorem, due to Knaster, Kuratowski and Mazurkiewicz in 1929, is a topological lemma reminiscent of Sperner’s lemma and Brouwer’s fixed point theorem. It has numerous applications in combinatorics, discrete geometry, economics, game theory and other areas. Generalizations of this lemma, in…
