On the Riemann curvature of diffeomorphism groups,One calculates explicitly the sectional curvatures of certain infinite-dimensional Lie groups equipped with left-invariant metrics whose geodesics correspond to flows of an ideal fluid. The sectional curvature turns out to be negative in certain two-dimensional directions.GLEAN 发表于 2025-3-31 03:53:25
Conditions for non-linear stability of stationary plane curvilinear flows of an ideal fluid,The present article demonstrates some hydrodynamical corollaries of three simple theorems in the theory of ordinary differential equations. In particular, we shall derive sufficient conditions for the stability of stationary, plane, curvilinear flows of an inviscid incompressible fluid with respect to finite perturbations.CLAM 发表于 2025-3-31 06:54:35
