A uniqueness result for infinite semipositone \(p\)-Laplacian problems in a ball. (English) Zbl 1506.34041

Uniqueness of positive radial solutions of singular \(p\)-Laplacian equations in a ball subject to the Dirichlet boundary condition is obtained when the parameter involved is large. The reaction terms which are not necessarily increasing or concave on \((0,\infty)\) exhibit infinite semipositone structures at zero.
