摘要
讨论了一类非局部退化抛物方程组ut=vp1(Δu+au∫Ωvq1dx),vt=up2(Δv+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.
The authors consider the blow-up phenomenon for a nonlocal degenerate system ut=v^p1(△u+au∫nv^q1dx),vt=u^p2(△v+bv∫n^u^q2dx) with Dirichlet boundary condition. Conditions on the existence of global and blow-up solution are obtained by using the super- and sub-solution techniques.
