Abstract

For an open, bounded domain \Om\Om in RN\mathbb{R}^N which is strictly convex with C2C^2 boundary, we show that there exists a >0\land>0 such that the singular quasilinear problem \begin{eqnarray*} &-\delp u =\cfrac{\lambda}{u^{\del}}+u^q\,\,\mbox{in}\,\,\Om\\ &u=0\,\,\mbox{on}\,\,\partial\Om;\, \,\,u>0\,\,\mbox{in}\,\,\Om \end{eqnarray*} admits atleast two solution u u and vv in Wloc1,p(\Om)L(\Om)W^{1,p}_{loc}(\Om)\cap L^{\infty}(\Om) for any \del>0\del>0 and 0<\lam<0<\lam<\land provided 1<p<N1<p<N and p1<q<p(N1)Np1p-1<q<\frac{p(N-1)}{N-p}-1.\\ Moreover the solutions uu and vv are such that u\alpu^{\alp} and v\alpv^{\alp} are in W01,p(\Om)W^{1,p}_0(\Om) for some \alp>0\alp>0.
