The study of differential operators within the framework of Lie groups offers a profound gateway into understanding symmetry, geometry and representation theory. At its core, this area investigates ...
Transactions of the American Mathematical Society, Vol. 358, No. 8 (Aug., 2006), pp. 3363-3383 (21 pages) We investigate microlocal properties of partial differential operators with generalized ...
We introduce a τ-dependent Wigner representation, Wig τ , $\text{Wig}_{\tau},\tau \in [0,1]$ , which permits us to define a general theory connecting time-frequency representations on one side and ...
