Title: Nonlocal fractional Monge—Ampère equations

Abstract: The Monge—Ampère equation is one of the most important partial differential equations as it plays a crucial role in several areas of analysis, geometry, and applied mathematics. We will present recent developments on the open question of finding an appropriate notion of a nonlocal, fractional Monge—Ampère equation.

Title: Some recent results on the control of invasive species

Abstract: The spread and control of invasive species/pests is a major societal, ecological and economic issue. In this talk I will discuss various results that focus on methods in biological control, such as the use of introduced predators to keep pest populations in check. I will also briefly delve into two species competitive systems, with some applications to refuge design.

Title: Gelfand-Tsetlin representations

Abstract: In 1925, Cartan obtained a classification of finite-dimensional irreducible representations of an arbitrary finite-dimensional complex reductive Lie algebra. We will review recent progress on the problem of classifying not necessarily finite-dimensional irreducible representations of Lie algebras and related algebras. Focus will be on the general linear Lie algebra (consisting of all square matrices) which is the most studied case, and for which notions can be made concrete. Towards the end we mention ongoing generalizations of the theory to quantum groups and beyond.
