Heteroclinic connections for a class of non-autonomous systems
L. Sanchez
Abstract:
We prove the existence of heteroclinic connections for a system
of ordinary differential equations, with time-dependent coefficients,
which is reminiscent of the ODE arising in connection with traveling
waves for the Fisher equation.
The approach is elementary and it allows in particular the
study of the existence of positive solutions for the same system that
vanish on the boundary of an interval
