摘要
研究了带齐次Dirichlet边界条件的非局部退化奇异半线性抛物方程组,建立了经典解的局部存在性与唯一性定理,在适当的假设下,得到了非负解的整体存在性与有限时刻爆破.
In this paper the authors investigate a nonlocal degenerate singular semilinear parabolic system with homogeneous Dirichlet conditions. The local existence and uniqueness of classical solution are established. Under appropriate hypotheses, the global existence and finite time blow-up of positive solution are obtained.
