Authors: AOMAR ANANE, OMAR CHAKRONE, ABDELLAH ZEROUALI

Abstract: In this paper we study the existence of the principal eigencurves for a nonselfadjoint elliptic operator. We obtain their variational formulation. We establish also the continuity and the differentiability of the principal eigencurves.

Keywords: Nonsefadjoint elliptic operator, principl eigenvalue, principl eigencurve, Holland's formula.
