| Abstract: | This paper is concerned with the existence, uniqueness and/or multiplicity, and stability of positive solutions of an indefinite weight elliptic problem with concave or convex nonlinearity. We use mainly bifurcation methods to obtain our results. |
| Keywords: | Indefinite weight elliptic problem nonlinear eigenvalue problem bifurcation method |
