In this paper we study the existence of global solutions to the Cauchy problem of nonlinear Schrodinger equation by establishing time weight function spaces and
In this note we shall give a simple proof of a result in [1] which gives a sufficient condition for the regularity of solutions to the Navier-Stokes equation in
In this paper, we consider the existence and nonexistence of positive solutions to semilinear elliptic equation -Δu = K(x)(1 - |x|)-λuq in the unit ball B wit
We investigate the asymptotic behaviour of solution of the initialboundary value problem for the equation, which describes the evolution of graphs with speed de
