제목: Time-asymptotic behavior towards viscous shocks for compressible Navier-Stokes equations.
초록: We investigate the well-posedness of the compressible Navier–Stokes equations with two different constant states prescribed as far-field conditions. In particular, we consider how classical solutions behave as time tends to infinity. Their time-asymptotic behavior is related to the associated Riemann problem for the compressible Euler equations. There are several types of Riemann solutions. Among these, we focus on shock waves.
시간: 10:00-11:00

제목: Unique Solvability and Stability for the Landau Equation with Inflow and Diffuse Reflection Boundary Conditions
초록: The Landau equation is a fundamental kinetic model for collisional plasmas. In this talk, I will discuss the Landau equation in a bounded domain under inflow and diffuse reflection boundary conditions. We establish a well-posedness theory for both the stationary and time-dependent problems, and prove the asymptotic stability of steady states under small perturbations. This is joint work with Chanwoo Kim.
