Title: Variational-Hemivariational Inequalities: Theory, Numerical Analysis, and Applications Abstract: 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 law...

All Day

In honor of Sonia Kovalevsky, the Department of Mathematics at the University of Iowa organizes Sonia Kovalevsky High School Mathematics Day yearly with the goal to inspire young women interested in math and show them that math is like solving a puzzle. Sonia Kovalevsky High School Mathematics Day is an opportunity for young women to engage in a day of networking, mentoring, and fun! The daylong program includes workshops, interactive talks, math related games and panels of professionals wit...

Title: Can Computational Modeling Inform Intervention Strategies to Mitigate the Impact of Developmental Abnormalities? Abstract: Branched, tree-like structures, such as the lung airways and mammary ducts, are vital for fluid transport in mammals. They facilitate the secretion and distribution of essential substances, as well as the removal of waste, thereby supporting diverse physiological functions. The formation of these tree-like structures typically begins during embryonic development....

Title: Quantum symmetries old and new.   Abstract: Quantum symmetries is the study of how symmetries of classical objects carry over to their quantizations.  In this lecture I will review the work of De Concini, Kac and Lusztig on how the coadjoint action of an algebra group G carries over to an action of a quantum group at a root of unity on its restricted dual at that root of unity. I will then resolve a recent conjecture in skein theory negatively by analyzing the quantum symmetri...

The Great Plains Operator Theory Symposium. From a modest beginning in 1981, the Great Plains Operator Theory Symposium (GPOTS) has become a major annual conference. It rotates between Universities in the U.S., with a new host university every year, and with NSF funding. For Spring 2026, it will be at the University of Iowa, a founding university. By now, GPOTS has evolved into a major international conference on operator theory and operator algebras. The symposium focuses on recent developm...
