Abstract
The paper deals with the Cauchy problem for a complete second-order differential equation with unbounded operator coefficientsu″+A(t)u′+B(t)u=f, u(0)=u0, u′(0)=u 1 . By using the “commutant method,” we construct a coercive solution of this problem in Holder space in the case where the operatorB is as “strong” as the operator A2.
