摘要:

By the Mountain Pass Theorem, we study existence and multiplicity of posi-tive solutions of p-laplacian equation of the form −Δpuλf(x, u), the nonlinearity f(x, u) grows as uσ at infinity with a singular coefficient, where σ∈ (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.

关键词: p-Laplacian, variational methods, Sobolev-Hardy exponents
