Abstract

In this work, we introduce a $$\varvec{\tau } $$ -dependent multilinear Wigner transform $$W_{\varvec{\tau }}$$ , $${\varvec{\tau }}\in [0,1]^d$$ . It also includes various types of multilinear time-frequency representations, among the others the classical multilinear Wigner and Rihaczek representations and some properties of multilinear $$\varvec{\tau } $$ -Wigner transform. We then prove the boundedness properties of multilinear $$\varvec{\tau } $$ -Wigner transform both on products of Lebesgue spaces and on modified version of modulation spaces.
