ZoomTitle: Free Boundary Problem: Challenges and Applications Abstract: There exists a wide range of modern and important physical and Biological phenomena that are described as free boundary problems. The difficulty in solving them stems from the fact that the solution depends on a boundary that evolves in time, at which boundary conditions must be imposed
Colloquium – Ralf Schiffler (University of Connecticut)
ZoomTitle: An Introduction to Cluster Algebras Abstract: Cluster algebras are commutative algebras with a special combinatorial structure. They were introduced in 2002 by Sergey Fomin and Andrei Zelevinsky in the context of canonical bases in Lie theory and have quickly developed deep connections to other areas of mathematics and physics, including combinatorics, representation theory, hyperbolic geometry, elementary

ZoomTitle: Basic reproduction number and principal eigenvalue Abstract: Basic reproduction number is a dimensionless constant which is used in epidemiology to determine if an emerging infectious disease can spread. Principal eigenvalue, a key concept in spectral theory, is used to reflect certain properties of matrices or differential operators. In this talk we will discuss some
AWM 2021 Colloquium – Lisa Piccirillo (Massachusetts Institute of Technology)
ZoomAbstract: There is a rich interplay between the fields of knot theory and 3- and 4-manifold topology. In this talk, I will describe a weak notion of equivalence for knots called concordance, and highlight some historical and recent connections between knot concordance and the study of 4-manifolds, with a particular emphasis on applications of knot
Colloquium – Lisa Traynor (Bryn Mawr)
ZoomTitle: Legendrian Torus and Cable Links Abstract: In contact topology, an important problem is to understand Legendrian submanifolds; these submanifolds are always tangent to the plane field given by the contact structure. In fact, every smooth knot type will have an infinite number of different Legendrian representatives. A basic problem is to give the “Legendrian
Colloquium – Wilfrid Gangbo, UCLA
ZoomTitle: Analytical Aspects of Mean Field Games Abstract: We highlight the isometry between the set of probability measures and the quotient of a Hilbert space. This allows to see that some important operators, such as the common noise operator in Mean Field Games, are nothing but partial Laplacians. We introduce to the so-called master equation
Colloquium – Peter Johnson (University of Virginia)
ZoomTitle: A zero surgery obstruction from involutive Heegaard Floer homology Abstract: A fundamental result in 3-manifold topology due to Lickorish and Wallace says that every closed, oriented, connected 3-manifold can be obtained by surgery on a link in the 3-sphere. One may therefore ask: which 3-manifolds can be obtained by surgery on a link with
