Abstract

In this article, we study two different types of operators, the localization operator and Weyl transform, on the reduced Heisenberg group with multidimensional center G\mathcal{G}. The group G\mathcal{G} is a quotient group of non-isotropic Heisenberg group with multidimensional center Hm\mathcal{H}^m by its center subgroup. Firstly, we define the localization operator using a wavelet transform on G\mathcal{G} and obtain the product formula for the localization operators. Next, we define the Weyl transform associated to the Wigner transform on G\mathcal{G} with the operator-valued symbol. Finally, we have shown that the Weyl transform is not only a bounded operator but also a compact operator when the operator-valued symbol is in Lp,1p2,L^p,1\leq p\leq 2, and it is an unbounded operator when p>2p>2.
