In this paper, a third order(in time) partial differential equation in R^n is con-sidered. By using semigroup method and constructing Lyapunov function, we establish the global existence, asymptotic behavior and uni...
In this paper, the fixed-point Theorem i s used to estimate an asymptotic solution of boundary value problems for a class o f third order quasilinear differential equation and the uniformly valid asymptot ic expansio...
In this paper we first obtain Some fixed point theorems and then app- ly them to a third-order periodically perturbed non-dissipative systems, conditions on the existence of multiple periodic solutions are given。 Fin...
In this paper, We give the sufficient conditions of the unstability of zero solution for the third order linear differential equation with periodic coefficients d^3x/dt^3+A(t)dx/dt+B(t)x=0.
