Real Integrability Conditions for the Nonuniform Exponential Stability of Evolution Families on Banay stable if there exist a positive real number . and a nondecreasing function . : ℝ. → ℝ. with .(.) positive for all positive . and such that for each . ∈ ., the following inequality . holds true for all . ∈ . with ‖.‖ ≤ 1. We arrive at the same conclusion under the assumption that there exist three

Validated Computations for Fundamental Solutions of Linear Ordinary Differential Equationswhich has a periodic potential. Our method is based on Floquet theory and Nakao’s verification method for nonlinear equations. We show how to enclose fundamental solutions together with characteristic exponents and give a numerical example.

Tight Enclosures of Solutions of Linear Systemswer and upper error bounds of the approximate solution is proposed. By the proposed method, it is possible to obtain the error bounds which are as tight as needed. As a result, it can be verified that the obtained error bounds are of high quality. Numerical results are presented elucidating properti
