Title: A model theorist’s perspective on the Connes Embedding Problem (and its resolution)Abstract: In 2020, a group of computer scientists resolved the Connes Embedding Problem (CEP) from von Neumann algebra theory. In this informal talk, I’ll explain how basic ideas from mathematical logic can be used to simplify and strengthen the resolution of the CEP from the computer science result.Professor Goldbring is giving a colloquium talk, Effective metric structure theory and operator algebras, at...

Title: Variational-Hemivariational Inequalities: Theory, Numerical Analysis, and ApplicationsAbstract: In recent years, modeling, mathematical analysis, and numerical solution of hemivariational inequalities, or more generally, variational-hemivariational inequalities, have attracted much attention in the research communities. Through the formulation of variational-hemivariational inequalities, application problems involving nonsmooth, monotone or non-monotone, multivalued constitutive laws...
