摘要 研究一类定义在区域(0,T)×Ω上的p-Laplacian椭圆抛物型偏微分方程pt(u)-▽·(|▽u|p-2▽u)=f(t,x)的解的存在性,Ω是RN的一个有界区域(N≥1),边界Ω是C2光滑的,其中p≥2,p(u(0,x))=p0.基于将原方程变形为次微分的形式pt(u(t))+φt(u(t))■f(t),利用两次逼近证明了解的存在性。 The article investigates the existence of solution to a class of p-Laplacian elliptic-parabolic equation ρ1(μ)-△↓·(|△↓u|p-2△u)=f(t,x) in (0,T)×Ω,where Ω∩→R^n with δΩ of C^2 class,p≥2,ρ(u(0,x))=ρ0,we prove the existence of solution by twice approximation on the base of transforming the original equation into sub-differential forms ρt(u(t))+δφ'(u(t))∈←f(t).
