Abstract
In this paper the spectral shift function (s.s.f.) for the pair of operators, generated by a canonical system of differential equations with two different boundary conditions, is studied. The main result is a connection between the s.s.f. and the spectral function. Also the inverse problem is studied: For a given s.s.f. we find a canonical system and investigate its uniqueness.
