Applying the homogeneous balance method, we have found the explicit and soliton solutions and given a successive formula of finding explicit solutions to the(2+
This paper is the parabolic counterpart of previous ones about elliptic operators in unbounded domains. Maximum principles for second-order linear parabolic equ
The first initial-boundary value problem for the following equation utt-αΔutt-2bΔut=αΔ^3u-βΔ^2u+Δu+γΔ(u^2) in a unit circle is considered. The existenc
