By the Mountain Pass Theorem, we study existence and multiplicity of posi- tive solutions of p-laplacian equation of the form - △pu =λf (x, u), the nonlinearity f (x, u) grows as u^δ at infinity with a singular coefficient, where a ∈ (p - 1,p* - 1). To manage the asymptotic behavior of its positive solutions with respect to λ, we establish a new Liouville-type theorem for the p-Laplacian operator. 展开更多
