Abstract:
In this article, we prove the existence and multiplicity of nontrivial
solutions for the nonperiodic perturbed fractional Hamiltonian systems
where
is a parameter,
,
and
are left and right Liouville-Weyl fractional
derivatives of order
on the whole axis
respectively,
the matrix
is not necessary positive definite for all
nor coercive,
and
small enough.
Replacing the Ambrosetti-Rabinowitz Condition by general superquadratic
assumpt ions, we establish the existence and multiplicity results for the
above system. Some examples are also given to illustrate our results.
