摘要
考虑如下的非齐次非线性抛物型方程具有正的非线性Neumann条件的初边值问题:ut-(a(u)u)=g(u),(x,t)∈Ω×[0,T)unST=f(u),(x,t)∈ST=Ω×[0,T),u(x,0)=u0(x)>0,x∈Ω,整体解存在和解的Blowup行为,解的这些行为的发生依赖于a(u),f(u),和g(u)的相互之间所给条件.
In this paper, we discuss the following problem:u t-(a(u)u)=g(u),\ \ \ \ \ (x,t)∈Ω× 0,T) un S T =f(u),\ \ \ \ \ \ \ (x,t)∈S T=Ω×[0,T), u(x,0)=u 0(x)>0,\ \ \ \ \ \ x∈Ω, and obtain three theorems,one is about the global solution,two are about the solution's blow up phenomena.
