Multiplicity of Solutions for a Class of Noncooperative Elliptic Systems ()
ABSTRACT
In this paper, we consider the following noncooperative elliptic systems
where
Ω is a bounded domain in
RN with smooth boundary
∂Ω, λ,δ,γ are real parameters, and
. We assume that
F is subquadratic at zero with respect to the variables
u,v. By using a variant Clark’s theorem, we obtain infinitely many nontrivial solutions
(uk,vk) with
as
k → ∞. Compared with the existing literature, we do not need to assume the behavior of the nonlinearity
∇F at infinity.
