The Compactness of Perturbed C-Semigroup
Ping Zhang · Journal of China University of Mining and Technology · 2002
In this paper,we discussed the compactness of perturbed C semigroup {S(t)} t≥0 generated by C semigroup {T(t)} t≥0 under perturbation of bounded linear operator (or positive operator) B ,and obtained a sufficient condition for eventual compactness of S(t)-T(t) .
