Abstract
We prove some statements on the decomposition of indefinite integrals of scalar functions with respect to a vector measure. We also consider continuous linear operators acting from the fundamental Banach space \(X\left( {T,{\sigma ,\mu }} \right)\) to a Hilbert space H. This gives a representation theorem for continuous linear operators from X to H. These results are applied to most general linear integral equations of the form \(\int\limits_T {x\left( t \right)dv = \varphi ,v:{\sigma } \to H,v \ll {\mu }}\). Such equations are equivalent to certain infinite systems of scalar integral equations and to infinite systems of linear algebraic equations. Bibliography: 11 titles.
