Abstract:

The authors study the existence of solutions for the nonlinear elliptic system

{  -M\+λ, ∧(D2u)=f(u, v)   in  Ω,   

   -M\+λ, ∧(D2v)=f(u, v)   in  Ω,   

   u ≥ 0, v ≥ 0                    in  Ω,

   u=v=0                            on  ∂Ω,

where Ω is a bounded convex domain in RN, N ≥ 2. It is shown that under some assumptions on f and g, the problem has at least one  positive solution (u,v).

Key words: fixed point index, nonlinear elliptic system, Pucci operator
