摘要

The main crux of this work is to define the Wigner transform associated with the Laguerre-Bessel operator and to give some results related to this transform. Next we introduce a new class of pseudo-differential operator \(\mathscr {L}_{u, v}(\sigma )\) L u , v ( σ ) called localization operator which depend on a symbol \(\sigma\) σ and two functions u and v. We give a criteria in terms of the symbol \(\sigma\) σ for its boundedness and compactness, we also show that these operators belongs to the Schatten-Von Neumann class \(S^p\) S p for all \(p \in [1; +\infty ]\) p [ 1 ; + ] and we give a trace formula.
