Abstract:
We study the properties of Rademacher chaos related to its “lacunarity”. It is proved that Rademacher chaos of arbitrary order d is a 2−d-uniqueness system as well as a system of strict convergence in the wide (not narrow) sense.
Keywords:
Rademacher functions, Walsh functions, Rademacher chaos, lacunary sequence, ε-uniqueness system, system of strict convergence.
