%0 Journal Article %T Asymmetric elliptic problems in $R^N$ %A Jean-Pierre Gossez %A Liamidi Leadi %J Electronic Journal of Differential Equations %D 2006 %I Texas State University %X We work on the whole $R^N$ and prove the existence of a first nonprincipal eigenvalue for an asymmetric problem with weights involving the p-Laplacian. As an application we obtain a first nontrivial curve in the corresponding Fucik spectrum. %K Principal eigenvalue %K indefinite weight %K unbounded domain %K p-Laplacian %K Fucik spectrum. %U http://ejde.math.txstate.edu/conf-proc/14/g1/abstr.html
