STRUCTURE OF GROUP C*-ALGEBRAS OF LIE SEMI-DIRECT PRODUCTS OF $ {\Bbb R} $ OR $ {\Bbb C} $ BY LIE GROUPS [PDF]

open access: yes
This paper is devoted to the case by case study on structure of group C*-algebras of the Lie semi-direct products of the 1-dimensional real or complex Lie groups by connected Lie groups, in particular, by commutative Lie groups or the generalized ...

Lagrangian structures and multidimensional consistency [PDF]

open access: yes, 2010
The conventional point of view is that the Lagrangian is a scalar object (or equivalently a volume form), which through the Euler-Lagrange equations provides us with one single equation (i.e., one per component of the dependent variable ...

Riemannian Geometry Framed as a Generalized Heisenberg Lie Algebra

open access: yes, 2019
The Heisenberg Lie algebra (HA) plays an important role in mathematics with Fourier transforms, as well as for the foundations of quantum theory where it expresses the operators of space-time, X, and their commutation rules with the momentum operators, D, that execute infinitesimal translations in X.
