講座主題：Incompressible flows with some geometric symmetry
主講嘉賓：劉繼濤
講座内容：
In this talk, we will briefly introduce background of the classical fluid dynamics equations and then mainly discuss two kinds of incompressible flows with special geometrical structure: the incompressible axisymmetric and helical symmetric flows. Specifically, we will introduce some new results on the two kind of flows, include the vanishing viscosity limit of axisymmetric viscous flow, the global well-posedness of inviscid axisymmetric flow, and the global well-posedness of helical symmetric flow with horizontal viscosities.
