Abstract:We discuss a novel approach to the mathematical analysis of equations with memory, based on a new notion of state. This is the initial configuration of the system at time t = 0 which can be unambiguously determined by the knowledge of the dynamics for positive times. As a model, for a nonincreasing convex function ${G : mathbb{R}^+ to mathbb{R}^+}We discuss a novel approach to the mathematical analysis of equations with memory, based on a new notion of state. This is the initial configuration of the system at time t = 0 which can be unambiguously determined by the knowledge of the dynamics for positive times. As a model, for a nonincreasing convex function G : mathbbR+ ? mathbbR+{G : mathbb{R}^+ to mathbb{R}^+} such that
$G(0) = lim_{sto 0}G(s) > lim_{stoinfty}G(s) >0 $G(0) = lim_{sto 0}G(s) > lim_{stoinfty}G(s) >0
