Abstract:
This article presents asymptotic conditions, under various sharp
and nonuniform nonresonance assumptions, for solving
the forced third order nonlinear system
,
in which
,
and other associated matrices are not necessarily
symmetric. This work generalizes some results in the literature
which are hinged basically on symmetry considerations.
