Bandlimited Wavelets on the Heisenberg Group
Vignon Oussa
Let be the three-dimensional Heisenberg group. We introduce a structure on the Heisenberg group which consists of the biregular representation of …
Computing Vergne Polarizing Subalgebras
Vignon Oussa
According to Kirillov's theory, the construction of a unitary irreducible representation of a nilpotent Lie group requires a precise computation of some polarizing subalgebra subor…
Unitary Representations of Lattices of Free Nilpotent Lie Groups of Step-Two
Vignon Oussa
Using a theorem proved by Bekka and Driutti, we show that if is a freely generated nilpotent Lie algebra of step-two, then almost every irreducible representation of…
Sampling Theorems for Some Two-Step Nilpotent Lie Groups
Vignon Oussa
Let be a simply connected, connected nilpotent Lie group with the following assumptions. Its Lie Lie algebra is an -dimensional vector space over the reals. M…
Regular Representations of Time-Frequency Groups
Azita Mayeli, Vignon Oussa
In this paper, we study the Plancherel measure of a class of non-connected nilpotent groups which is of special interest in Gabor theory. Let be a time-frequency group. More pr…
