Abstract:
This article concerns the existence of solutions for the
fractional Hamiltonian system
where
,
is a symmetric and positive definite matrix.
The novelty of this article is that if
and the nonlinearity
involves a combination of superquadratic
and subquadratic terms, the Hamiltonian system possesses at least two
nontrivial solutions.
