Abstract:
We study the relation between the condition \[ \sup \limits _{T > 0} \int _{[0,T]} {\bar \varphi (t)} \int _{[t - T,t]} {\varphi (t - s)\;dv (s)\;dt < \infty } \] and the asymptotic behavior of the bounded function $\varphi$ when $\nu$ is a positive definite measure. Earlier we have proved that if $\nu$ is strictly positive definite and $\varphi$ satisfies a tauberian condition, then $\varphi (t) \to 0$ as $t \to \infty$. Here we characterize the spectrum of the limit set of $\varphi$ in the case when $\nu$ is not strictly positive definite. Applying this theory to a nonlinear Volterra equation we get some new results on the asymptotic behavior of its bounded solutions.References
