A class of two-level high-order accuracy explicit difference scheme for solving 3-D parabolic P.D.Eis constructed.Its truncation error is (△t^2+△x^4)and the s
In this paper,a class of strongly nonlinear singular perturbed boundary value problems are considered by the theory of differential inequalities and the correct
J. L Lions and W. A. Stranss [1] have proved the existence of a global solution of the initial boundary value problem for nonlinear generalized Euler-Possion-Da
