On the discrete Wigner function for SU(N)
(Iop Publishing Ltd, 2019-10-04)
We present a self-consistent theoretical framework for finite-dimensional discrete phase spaces that leads us to establish a well-grounded mapping scheme between Schwinger unitary operators and generators of the special ...
Deformations of the discrete Heisenberg group

Symmetry and Inverse Closedness for Some Banach ∗-Algebras Associated to Discrete Groups
(Tusi Mathematical Research Group, 2015)
A discrete group G is called rigidly symmetric if for every C*-algebra A the projective tensor product l(1)(G)(circle times) over capA is a symmetric Banach *-algebra. For such a group we show that the twisted crossed ...

Discrete generator coordinate: Symmetry restoration in finite-dimensional spaces
(1999-12-01)
Group theoretical-based techniques and fundamental results from number theory are used in order to allow for the construction of exact projectors in finite-dimensional spaces. These operators are shown to make use only of ...

Lagrangian reduction of nonholonomic discrete mechanical systems
(American Institute of Mathematical Sciences, 2010-03)
In this paper we propose a process of lagrangian reduction and<br />reconstruction for nonholonomic discrete mechanical systems where the action of a continuous symmetry group makes the configuration space a principal ...
Homological invariants for pro-p groups and some finitely presented pro-l groups
