Infinitely many arbitrarily small positive solutions for the Dirichlet problem involving the \(p\)-Laplacian. (English) Zbl 1064.35053
The authors present a result of existence of infinitely many arbitrarily small positive solutions to the Dirichlet problem involving the \(p\)-Laplacian: \[ -\Delta_pu=\lambda f(x,u)\text{ in }\Omega\qquad u=0\text{ on } \partial \Omega, \] where \(\Omega\in {\mathbb R}^N\) is a bounded set with sufficiently smooth boundary \(\partial \Omega\), \(p>1\), \(\lambda>0\), and \(f:\Omega\times \mathbb R\to \mathbb R\) is a Carathéodory function satisfying the condition: there exists \(\bar{t}>0\) such that \[ \sup_{t\in[0,\bar t\, ]} f(\cdot,t)\in L^{\infty}(\Omega). \] {In the corrigendum several errors are corrected, esp. “a.e. positive” has to be changed into “nonzero and nonnegative”}.
