In this paper, we deﬁne the Wigner-Ville distribution function (WVDF) and corre-
sponding Weyl operator in the linear canonical transform (LCT) domain. Further, we
examine Moyle identity for the WVDF and investigate some of its properties. More-
over, we discuss the boundedness and compactness of Weyl operator on the Lpspace
in the LCT domain.

In quantum mechanics, the Wigner-Weyl transform is the invertible mapping between
functions in the quantum phase space formulation and Hilbert space operators in
the Schrödinger picture. This mapping was originally devised by Hermann Weyl in
1927 on an attempt to map symmetrized classical phase space functions to operators in
quantum mechanics, a procedure known as Weyl quantization . But the map merely
amounts to a change of representation within quantum mechanics inspite of classical
to quantum quantities .
