Abstract

We study the degenerate semilinear elliptic systems of the form - div ( h 1 ( x ) u ) = λ ( a ( x ) u + b ( x ) v ) + F u ( x , u , v ) , x Ω , - div ( h 2 ( x ) v ) = λ ( d ( x ) v + b ( x ) u ) + F v ( x , u , v ) , x Ω , u | Ω = v | Ω = 0 , where Ω R N ( N 2 ) is an open bounded domain with smooth boundary Ω , the measurable, nonnegative diffusion coefficients h 1 , h 2 are allowed to vanish in Ω (as well as at the boundary Ω ) and/or to blow up in Ω ¯ . Some multiplicity results of solutions are obtained for the degenerate elliptic systems which are near resonance at higher eigenvalues by the classical saddle point theorem and a local saddle point theorem in critical point theory.
