In this paper,we consider the complex Ginzburg-Landau equation (CGL) in three spatial dimensions ut=ρu+(1+iγ)△u-1+iμ—|u|^2σu,(1) u(0,x)=u0(x),(2) where
The singularly perturbed problem for the semilinear elliptic equations is considered.Under appropriate conditions.by using the comparison theorem,the existence
