Positive solutions for classes of multiparameter elliptic semipositone problems

We study positive solutions to multiparameter boundary-value problems of the form egin{gather*} - Delta u =lambda g(u)+mu f(u)quad ext{in } Omega \ u =0 quad ext{on } partial Omega , end{gather*} where $lambda >0$, $mu >0$, $Omega subseteq R^{n}$; $ngeq 2$ is a smooth bounded domai...
