【期刊论文】Evolutionary weighted p-Laplacian with boundarydegeneracy ✩
王春朋, Yin Jingxue, Wang Chunpeng ∗

The paper concerns the well-posedness problem of an evolutionary weighted p-Laplacian with boundary degeneracy. Different from the classical theory for linear equations, it is shown that the degenerate portion of the boundary should be decomposed into two parts: the strongly degenerate boundary on which the equation exhibits hyperbolic characteristics and the weakly degenerate boundary on which the equation still exhibits parabolic characteristics. We formulate reasonably the boundary value condition and establish the existence and uniqueness theorems.

【期刊论文】Uniqueness of the bounded solution to a strongly degenerateparabolic problemI

This paper concerns the uniqueness of the bounded solution to a strongly degenerate parabolic problem. The equation consideredmay have two kinds of strong degeneracies and there is no restriction on the relation between the two degeneracies. By usingHolmgren’s approach, we prove that the bounded solution of the associated initial–boundary value problem is unique under someessentially necessary condition on the growth of the convection.

This work is concerned with the critical exponent of the non-Newtonian polytropic filtration equation with nonlinear boundary conditions. We obtain the critical global existence exponent and critical Fujita exponent by constructing various self-similar supersolutions and subsolutions.

In this paper we study self-similar solutions to the singular and degenerate diffusion equation ut=(|(p(u))x|−2(p(u))x)x, −∞<x<+∞, t>0, where 1<_<2. The existence and uniqueness for the solutions are established. In addition, the asymptotic behavior is investigated.
