Abstract :
New conditions for the exponential stability of a linear finite-dimensional system as well as a class of infinite-dimensional systems described by parabolic partial differential equations are derived. It is shown for finite-dimensional systems that the frozen time analysis is justifiable for the systems that satisfy the Holder-type continuity, which is a broader class than the class of slowly varying systems. For parabolic systems, the restrictive condition, such as the existence of A(∞), has ben removed. The proofs are carried out using the semigroup theory and the variation of constant formulas, and specific bounds for constants such as K and L are given
