We study computability of the abstract linear Cauchy problem (1)where A is a linear operator, possibly unbounded, on a Banach space X . We give necessary and sufficient conditions for A such that the solution operator K : x ↦ u of the problem ( 1) is computable. For studying computability we use the representation approach to computable analysis developed by Weihrauch and others. This approach is consistent with the model used by Pour‐El/Richards.
