Unconditional bases for homogeneous $\alpha$-modulation type spaces

Functional Analysis 2020-11-30 v1

Abstract

In this article we construct orthonormal bases compatible with bi-variate homogeneous α\alpha-modulation spaces and the associated spaces of Triebel-Lizorkin type. The construction is based on generating a separable α\alpha-covering and using carefully selected tensor products of univariate brushlet functions with regards to this covering. We show that the associated systems form an unconditional bases for the homogeneous α\alpha-spaces of Triebel-Lizorkin type.
