We consider the singular boundary value problem
where , h(x) is a given function and V(x) has prescribed finitely many singular points. Our goal in this paper is to establish some existence and multiplicity results for above problem when μ∈(0,μ⁎) for some μ⁎>0 and obtain exact estimate for extremal value μ⁎=μ⁎(Ω,γ,2⁎,h(x))>0 for above problem.
