Commutative diagrams and tensor calculus in Riemann spaces

Il Nuovo Cimento B, 1993
The basic rules of tensor analysis in non-Euclidean spaces are derived by means of the formalism of commutative diagrams (widely used in many branches of mathematics, especially the theory of categories). We consider here as an example the case of general relativity (although this approach can be applied to gauge theories as well).

Non-commutative differential calculus and q-analysis

Journal of Physics A: Mathematical and General, 1992
Summary: Starting from the formulation of covariant non-commutative differential calculus recently given by Wess and Zumino we construct a deformation of the Virasoro algebra, which allow us to identify the variables and differential operators on the quantum plane \(\mathbb{R}^ 2_ q\) to those on the classical plane \(\mathbb{R}^ 2\).

Commutator Calculus for Wreath Product Groups

Communications in Algebra, 2015
We introduce a class of function spaces consisting of integer-valued functions of several integers which coordinatize the elements of certain subgroups of some finite regular wreath product groups. On each function space, we define operators which correspond to forming certain commutators relevent to computing the upper central series.
