The aim of this paper is to study the continuity of weak solutions for quasilinear degenerate parabolic equations of the form U_t-Δφ(u)=O, whereφ■C~1(R~1)is a strictly monotone increasing function.Clearly,the above equation has strong degeneracy,i.e.,the set of zero points ofφ′(·)is permitted to have zero measure. This is an answer to an open problem in[13,p.288]. 相似文献

In the middle of 1980s,Ni&Serrin,Grads,Ni &Nirenberg,established a generalized iueqnality for the sphelrical symmetry Solutions of quasilinear elliptic equations diV[A(|Du|)] ,f(u)=0,χ∈~n (1) By using this inequality,the results that do not exist spherical symmetry solution can be Proved.In order to study the non-existence of the nonspherical symmetry Solutions,We must establish the Pohozaev' ideutity or inequality for general nonspherical symmetry SOlutions for the most general quasilinear Euler equations 相似文献

This paper is concerned with a popular form of Cahn-Hilliard equation which plays an important role in understanding the evolution of phase separation. We get the existence and regularity of a weak solution to nonlinear parabolic, fourth order Cahn-Hilliard equation with degenerate mobility M(u)=um(1-u)m which is allowed to vanish at 0 and 1. The existence and regularity of weak solutions to the degenerate Cahn-Hilliard equation are obtained by getting the limits of Cahn-Hilliard equation with non-degenerate mobility. We explore the initial value problem with compact support and obtain the local non-negative result. Further, the above derivation process is also suitable for the viscous Cahn-Hilliard equation with degenerate mobility. 相似文献
