摘要: 讨论了一类非局部退化抛物方程组ut=vp1(Δ u+au∫Ωvq1dx), vt=up2(Δ v+bv∫Ωuq2dx)的解的爆破性质, 并利用上、 下解方法得到了解的整体存在与爆破的条件.

Abstract: The authors consider the blow-up phenomenon for a nonlocal degenerate system ut=vp1(Δu+au∫Ωvq1dx), vt=up2(Δv+bv∫Ωuq2dx) with Dirichlet boundary condition. Conditions on the existence of global and blow-up solution are obtained by using the super- and sub-solution techniques. -
