Colloquium – Shuyu Sun (King Abdullah University of Science and Technology)

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

Francis Su Harvey Mudd College Title: Sperner's Lemma: Old and New Abstract: Sperner’s Lemma is perhaps best known as a combinatorial equivalent of the Brouwer fixed point theorem. In this talk, I’ll survey old and new proofs of

Title: Cluster Algebras and Quiver Grassmannians Abstract: Since their conception, cluster algebras have made appearances in different fields such as algebra, combinatorics, geometry, and topology. For example, a class of objects from representation theory called quiver Grassmannians have been useful in describing the generators of cluster algebras using the Euler characteristic. This has motivated the

Title: Stability of Nonlinear Waves in Hamiltonian PDE Abstract: Nonlinear dispersive wave equations arise as reduced mathematical models from governing equations of mathematical physics, such as the Navier-Stokes and Maxwell equations. These reduced models combine the leading-order balance between nonlinear and dispersive effects present in wave propagation. The existence and stability of coherent structures such
