regulated functions; linear prolongation along an increasing function; analogue of Helley's principle of choice theorem; Banach space
Summary:
The first section consists of auxiliary results about nondecreasing real functions. In the second section a new characterization of relatively compact sets of regulated functions in the sup-norm topology is brought, and the third section includes, among others, an analogue of Helly's Choice Theorem in the space of regulated functions.
