Global existence and blow-up analysis for some degenerate and quasilinear parabolic systems
This paper deals with positive solutions of some degenerate and quasilinear parabolic systems not in divergence form: u1t = f1(u2)(∆u1 + a1u1), · · ·, u(n−1)t = fn−1(un)(∆un−1 + an−1un−1), unt = fn(u1)(∆un+anun) with homogenous Dirichlet boundary condition and positive initial condition, where ai (i = 1, 2, ···, n) are positive constants and fi (i = 1, 2, ···, n) satisfy some conditions. The lo...

This paper establishes a new criterion for global existence and nonexistence of positive solutions of the non-local degenerate parabolic system ut = v p ( ∆u+ a ∫
متن کاملExistence and Nonexistence of Global Solutions of Degenerate and Singular Parabolic Systems
where p,q > 1 and u(x,0) = u0(x), v(x,0) = v0(x), x ∈ R. Systems like (1.1) and (1.2) will be called degenerate and singular, respectively. Several authors have addressed this problem recently: we refer the interested reader to the papers by Levine [4] and Deng and Levine [1] for a survey of the literature on this subject. In the proofs we follow the technique developed by Mitidieri and Pohozae...

The paper deals with the existence and nonexistence of positive radial solutions for the weakly coupled quasilinear system div (
متن کاملExistence and Nonexistence of Positive Solutions for Quasilinear Systems
The paper deals with the existence and nonexistence of positive solutions for a class of p-Laplacian systems. We investigate the effect of the size of the domain on the existence of positive solution for the problem in sublinear cases. We will use fixed point theorems in a cone.
