Abstract:
In this paper, we introduce a new class of function systems generalizing the classical Faber–Schauder system. Under the condition that the generating sequence is bounded, we show that systems of such a class constitute bases in the space of continuous functions and prove some properties of series expansions of functions in these systems.
Keywords:Faber–Schauder function system, piecewise linear function, Vandermonde determinant, modulus of continuity, modulus of smoothness.
