Abstract

We consider a linear first-order ordinary operator-differential equation A(t)u′(t) + B(t)u(t) = f(t) in a Banach space, where the operator A(t) is not invertible in general. Sufficient conditions for the existence, uniqueness, and well-posedness of the Cauchy problem for this equation are obtained.
