This paper mainly deals with an initial-oblique derivative problem for nonlinear nondivergent parabolic systems of second order equations with measurable coefficients in a multiply connected domain.

An oblique derivative problem for degenerate hyperbolic equation of second order;

First we give a priori estimates of the solutions for the oblique derivative problem,then set operators,use the theory of integral operator and fixed point theory,proved that the existence and uniquence and give the solvability condition.

We consider the initial boundary problem for a class of nonlinear schrodinger equations with effect of dissipation and magnectic: i■_■=△■+q(|■|~2)■+η■×(■+■)-1/2γ(t)■.

In this paper we prove the strong asymptotic stability of global solution to the initial boundary problem for nonlinear degenerate wave equation by means of the method in M.

We prove the asymptotic behavior of initial boundary problem for a class of quasilinear wave equation by energy method.

Separation of variables method for fractional diffusion-wave equation with initial-boundary value problem in three dimensions;

Structure of global weak entropy solution for initial-boundary value problems of scalar conservation laws with non-convexity conditions;

This paper studies the Blow-up behavior of the initial-boundary value problem for the nonlinear reaction-diffusion equation: u_t= Δ u+f(u) , and proves that the smooth solutions can only exist in a limited extent of time.
