Based on the analogy to gas dynamics,the kinetic flux flux vector splitting (KFVS) method is used to stimulate the shallow water wave equations,The flus vectors
Let g(n) denote the least integer such that among any g(n) points in general position in the plane there are always n points in convex position.In this paper we
In this paper we obtain some formulas for totally umbilical submanifolds in a locally symmetric manifold, and derive some local results on the submanifolds from
