报告题目： Global large strong solutions to the 2D radially symmetric compressible Navier-Stokes equations on bounded domain
摘要：In this talk, I will present our recent result the 2D radially symmetric compressible Navier-Stokes equations with density-dependent viscosity. Under the condition of beta>1, we prove the global existence of the radially symmetric strong solutions to the Kazhikhov models under Dirichlet boundary conditions for arbitrary large initial data. This improves the previous results of previous results for general 2D domains where $\beta>4/3$ is required to ensure global existence. This is the first result concerning the global existence of classical solutions to the radially symmetric compressible Navier-Stokes equations in 2D solid balls under Dirichlet boundary condition.
