Abstract

The main aim of this work is to study important local Banach space constants for Boolean cube function spaces. Specifically, we focus on BSN\mathcal{B}_{\mathcal{S}}^N, the finite-dimensional Banach space of all real-valued functions defined on the NN-dimensional Boolean cube {1,+1}N\{-1, +1\}^N that have Fourier--Walsh expansions supported on a fixed~family S\mathcal{S} of subsets of {1,,N}\{1, \ldots, N\}. Our investigation centers on the projection, Sidon and Gordon--Lewis constants of this function space. We combine tools from different areas to derive exact formulas and asymptotic estimates of these parameters for special types of families S\mathcal{S} depending on the dimension NN of the Boolean cube and other complexity characteristics of the support set S\mathcal{S}. Using local Banach space theory, we establish the intimate relationship among these three important constants.
