Abstract

We discuss the problem of establishing dissipative estimates for certain differential equations for which the usual methods do not work. The aim of this paper are some new nonlinear integral inequalities leading to suitable uniform (with respect to time and the arameter ε ) bounds on the solutions to problems x(t) = f(t,x(t))+gε(t,x(t)), t ≥ 0 where f, gε: R+ × Rn → Rn are supposed to be piecewise continuous in time, locally Lipschitz in x, for any fixed ε ≥ 0. These problems are seen as perturbation to x(t) = f(t,x(t)), t ≥ 0. Furthermore, some examples are given to illustrate the applicability of the obtained results.
