摘要 讨论椭圆方程的Robin问题-Δu+au=f,inΩ, u n+αu=0,on Ω,这里a≥0,α≥0,且至少有一个不恒为0.若Ω是光滑凸域,弱解u∈H2(Ω),证明了第二基本估计‖u‖2,Ω≤c‖f‖0,Ω. An elliptic Robin's problem -Δu+au=f in Ω,un+αu=0,on Ω,is discussed,a≥0,α≥0,and one of them at least does not disappear. If Ω is a smooth convex domain and weak solution u∈H2(Ω),then second basic estimate ‖u‖2,Ω≤c‖f‖0,Ω is proved.
