DCDS

We study the problem of existence and multiplicity of subharmonic
solutions for a second order nonlinear ODE in presence of
lower and upper solutions. We show how such
additional information
can be used to obtain more precise multiplicity results.
Applications are given to pendulum type equations and to
Ambrosetti-Prodi results for parameter dependent equations.

DCDS

We prove the existence of multiple periodic
solutions as well as the presence of complex profiles (for a
certain range of the parameters) for the steady-state solutions
of a class of reaction-diffusion equations with a
FitzHugh-Nagumo cubic type nonlinearity. An application is given
to a second order ODE related to a myelinated
nerve axon model.

DCDS

We prove the existence of bounded solutions to
second order differential equations of Liénard type under
asymptotic conditions generalizing recent results of Ahmad and
Ortega.

DCDS

The existence
of periodic solutions for some
planar systems is investigated. Applications are
given to positive solutions for a class of Kolmogorov systems
generalizing a predator - prey model for the
dynamics of two species in a periodic environment.
