ZoomTitle: The second term in knot Floer homology Abstract: It is well known that the genus g of a knot is the highest Alexander grading for which the knot Floer homology is nontrivial. In recent years, there is evidence suggesting that the knot Floer homology is also nontrivial in the Alexander grading g-1. In this talk, I

ZoomTITLE: Revealing the mechanisms of molecular motors’ motility by using computational approaches ABSTRACT: Dynein is a molecular motor for cargo transportation and force generation in cells. Dysfunction of dynein is associated with many diseases, such as ciliopathies, lissencephaly and other neurodegeneration disorders. Understanding the functions of dynein is crucial for developing new treatments of such

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Matrix weights, the convex-set valued maximal operator, and Rubio de Francia extrapolation 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 overview of

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

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
