Title：Local-in-time well-posedness for 2D compressible magneto-micropolar boundary layer equations in Sobolev spaces

Speaker：Yuming Qin (Donghua University)

Time：10:00-11:00, Mar. 29, 2026

Location：Room 501, Huixing Building

Abstract：In this talk, we consider the two-dimensional compressible magneto-micropolar boundary layer equations on the half-plane, which are derived from 2D compressible magneto-micropolar fluid equations with the non-slip boundary condition on velocity, Dirichlet boundary condition on micro-rotational velocity and perfectly conducting boundary condition on magnetic field. Based on a nonlinear coordinate transformation, we first prove the local-in-time well-posedness for the compressible magneto-micropolar boundary layer system in Sobolev spaces, provided that initial tangential magnetic field is non-degenerate.
