应数学与统计学院邀请,河南师范大学杨新光教授将来我院作学术报告。
报告题目:Determination and reduction of 2D incompressible Navier-Stokes equations on Lipschitz domain and some functional PDEs
报告摘要:This talk is concrned with the following topics:(1) The number of determining modes is estimated for the 2D Navier-Stokes equations subject to an inhomogeneous boundary condition in Lipschitz domains by using an appropriate set of points in the configuration space to represent the flow by virtue of the Grashof number and the measure of Lipschitz boundary based on a stream function and some delicate estimates. (2) The number of determining modes for a class of functional evolutionaryPDEsis estimated by using an appropriate set of points in the configuration space by virtue of the generalized Grashof number via (a new retarded) averaging Gronwall inequality.
