摘要

In this paper, we consider a boundary value problem for Hale type differential inclusions of fractional order \(\alpha \in (1,2)\) α ( 1 , 2 ) in a separable Banach space under the assumption that the linear part of the inclusion is a generator of a uniformly bounded strongly continuous family of cosine operator functions and the nonlinear part is a causal multivalued operator. Based on the fixed point theory for condensing maps, we establish the global existence of a mild solution to this problem.
