Abstract
The aim of this lecture is to give a survey on spline expansions and their applications to function spaces. It concerns the questions for spline systems of being bases, unconditional bases, equivalent bases, bases with shift property, interpolating bases and the a.e. convergence of the spline expansions. These properties of the spline systems are discussed in various classical function spaces on the unit interval, one-dimensional torus, disc, cube, multi-dimensional torus and polydisc. The lecture covers mainly the works related to the author’s own investigations.
