设Ω是rn的一个有界开子集。讨论了连续函数f: R→R的条件,保证问题- Δu = λ λ f (u)在h1 (Ω)中对任意正实λ有无限多弱解。
Abstract Let Ω be a bounded open subset of R n . We discuss conditions on the continuous function f : R → R ensuring that the problem − Δu = λ ċ f ( u ) admits unboundedly many weak solutions in H 1 0 ( Ω ) for any positive real λ .
