Colloquium – Dan Margalit (Georgia Institute of Technology)
ZoomTitle: Algebraic, geometric, and dynamical aspects of surfaces Abstract: Taffy pullers, lab stirrers, and paint mixers are complicated dynamical systems. To any such system we can ascribe a real number, called the entropy, which describes the amount of mixing being achieved. Which real numbers arise, and what do they say about the dynamics of the

ZoomTitle: Matrix weights, the convex-set valued maximal operator, and Rubio de Francia extrapolation part 2. Abstract: In this series of talks (I project three), I want to talk about the theory of matrix weights: its history and motivation, and some recent results by myself, Kabe Moen, and others. The ultimate goal is to give an

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Fixed Q under the reverse operation in the RSK correspondence Abstract: The RSK correspondence is a bijection between permutations and pairs of standard Young tableaux with identical shape, where the tableaux are commonly denoted $P$ (insertion) and $Q$ (recording). It has been an open problem to demonstrate where $w^r$ is the reverse permutation
Colloquium – Rosa Orellana (Dartmouth College)
ZoomTITLE: Products of characters of the symmetric group ABSTRACT: One of the main open problems in combinatorial representation theory of the symmetric group is to obtain a combinatorial interpretation for what are known as the Kronecker coefficients. The Kronecker coefficients are obtained when we decompose the tensor product of two irreducible representations of the symmetric

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Computation of extension spaces in $kQ$-mod, for $kQ$ the path algebra of a quiver $Q$ of type $\tilde A(n-1,1)$, using planar curves. Abstract: The representation theory of quivers is important to the representation theory of associative algebras in general. If $Q$ is a quiver of affine type $\tilde A(n-1,1)$ and $k$ a fixed algebraically

ZoomTitle: The non-orientable 4-ball genus of torus knots Abstract: The non-orientable 4-ball genus of a knot $K$ in $S^3$ is the minimal first Betti number of any smoothly embedded non-orientable surface in $B^4$ bounded by K. This is the non-orientable analog of the 4-ball genus of $K$ (i.e. the minimal genus of any smooth orientable surface

Algebra/Topology Seminar – Surena Hozoori (Georgia Tech)
ZoomTitle: On Anosovity, divergence and bi-contact surgery Abstract: I will revisit the relation between Anosov 3-flows and invariant volume forms, from a contact geometric point of view. Consequently, I will give a contact geometric characterization of when a flow with dominated splitting is Anosov based on its divergence, as well as a Reeb dynamical interpretation
Colloquium – David Goldberg (Math Alliance, Purdue University)
ZoomAbstract: The National Alliance for Doctoral Studies in the Mathematical Sciences, more commonly known as the Math Alliance, grew out of an earlier NSF Funded project, The Alliance for the Production of African American PhDs in the Mathematical Sciences. In 2006 this project transformed itself to have a national scope, and it has been growing
