摘要
研究了带非线性边界条件 u n =up·vq, u n=ur·vs的非线性抛物型方程组ut =Δum,vt =Δvm(m ≥1)时的爆破问题 .获得了其解爆破的几个充分条件 .
A study is made on the blowing up problem for the nonlinear parabolic equations u t=Δu m,v t=Δv m, m≥1,with nonlinear boundary conditions u n=u p·v q, v n=u r·v s. Some sufficient conditions for its solution blow up are obtained.
