Title : De Giorgi's Minimizing MovementsSpeaker : Dohyun Kwon (University of Seoul)Abstract : The study of gradient flows holds significant importance across various fields, including partial differential equations, optimization, and machine learning. In this talk, we aim to explore the relationship between gradient flows and their timediscretized formulations, known as De Giorgi's minimizing movements scheme. We focus on how De Giorgi's minimizing movements coincide with gradient flows in two different spaces: the space of sets and the space of probability measures called Wasserstein space. Then, we discuss their implications for the wellposedness and longtime behavior of some PDEs, including mean curvature flow and the nonlinear FokkerPlanck equation.

Title : Degenerate/Singular Partial Differential EquationsSpeaker : KiAhm Lee (Seoul National University)Abstract : In this talk, we are going to consider various degenerate or singular operatorin partial differential equations related to free boundary problems and mathematical finance.We will discuss its underlined geometry and how the generalized polynomials appears in the regularity theory.
04/05 15:00 Kyeong Hun Kim (Korea university)
Title : Parabolic PDEs and SPDEs with spacetime nonlocal operatorsSpeaker : Kyeong Hun Kim (Korea University)Abstract : Parabolic equations are related to time dependent natural phenomena. For instance, the classical heat equation with local operators describes the normal diffusion. On the other hand, the description of abnormal diffusion and randomly moving particles with jumps requires the use of nonlocal operators.In this talk, I will give a short introduction to the parabolic PDEs and stochastic PDEs having nonlocal operators with respect to time and space variables.

Title : Enumerative geometry of curves and surfaces Speaker : YoungHoon Kiem (KIAS) Abstract : Enumerative geometry is the study of questions like “How many geometric figures of fixed topological type satisfy certain given conditions?” It is one of the oldest subjects in mathematics dating back to Apollonius, 22 centuries ago. In 1900, Hilbert included the Schubert calculus, enumerative geometry of linear subspaces, as the fifteenth in his famous list of 23 problems for the coming century. About 30 years ago, enumerative geometry of curves was revolutionized by conjectures generated by string theory, many of which are now firmly established mathematical theorems. By a technical breakthrough only a few years ago, we now have a modern surface counting theory. In this colloquium, I’d like to convey some of the key ideas in classical and modern enumerative geometry.
