Abstract
We investigate the abstract evolution equation of fractional order Dau = au, a > 0, where Da is the Caputo fractional derivative of order a and A is an unbounded closed operator in a Banach space X. Some perturbation properties are presented, generalizing known facts about Co-semigroups and cosine operator functions.
