    Existence of a Nonautonomous SIR Epidemic Model with Age Structure

    A nonautonomous SIR epidemic model with age structure is studied. Using integro-differential equation and a fixed point theorem, we prove the existence and uniqueness of a positive solution to this model. We c...

    Notes on the Propagators of Evolution Equations

    We consider the propagator of an evolution equation, which is a semigroup of linear operators. Questions related to its operator norm function and its behavior at the critical point for norm continuity or compact...

    Pairs of Function Spaces and Exponential Dichotomy on the Real Line

    We provide a complete diagram of the relation between the admissibility of pairs of Banach function spaces and the exponential dichotomy of evolution families on the real line. We prove that if
