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

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

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

ZoomTitle: Friezes, Quiver Representations and Cluster Theory Abstract: After cluster algebras were introduced by Fomin and Zelevinsky, there were many new connections found among many fields of mathematics: combinatorics, representation theory, quiver representations, non-commutative algebra, poisson theory and much more. Friezes were introduced by Conway and Coxeter as a very combinatorial notion. Since the introduction of cluster

346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Fractals and Syzygies Abstract: Syzygies are objects invented and utilized by David Hilbert in 1890 to study relations among polynomial equations, and have played a big role in the development of modern algebraic geometry. The quest to understand patterns of syzygies is both challenging and interesting, and sometimes reveals unexpected connections to other branches

Title: Bound-Preserving and Phase-wise Conservative Schemes for Incompressible Two-Phase Flow in Porous Media with Multiple Capillary Pressure Functions Abstract: Two or multiple phases commonly occur as fluid mixture in petroleum industry, where oil, gas and water are often produced and transported together. As a result, petroleum reservoir engineers spent great efforts in the development and
