摘要：
We prove the existence of a positive radial solution to the (p, q) Laplacian problem {-Delta(p)u - Delta(q)u = lambda f(u) in Omega, u = 0 on partial derivative Omega, where p > q > 1, Delta(r)u = div(vertical bar Delta u vertical bar(r-2)del u), Omega = B(0, 1) is the open unit ball in R-n, f:(0, infinity) -> R is p-sublinear at infinity with possible singularity and infinite semipositone structure at 0, and lambda > 0 is a large parameter.
