Existence and multiplicity results for a class of p-Laplacian problems with Neumann–Robin boundary conditions

On the Positive and Negative Solutions of Laplacian BVP With Neumann Boundary Conditions

“…Also by using a quadrature method, we obtain our results. In [2] and [7] for semipositone problems with p-Laplacian operator, existence and multiplicity results have been established with Neumann boundary value conditions and Dirichlet boundary value conditions, respectively. In [5], for semipositone and positone problems have been studied by Anuradha, Maya and Shivaji by using a quadrature method with Neumann-Robin boundary conditions and Laplacian operator.…”
