Commutator Calculus and the Lower Central Series
Studies in the History of Mathematics and Physical Sciences, 1982In 1933, there appeared a 66-page paper by P. Hall with the title A contribution to the theory of groups of prime power order. Its introduction describes it as “the first stages of an attempt to construct a systematic general theory of groups of prime power order.” These groups are also called p-groups, where, if p is not specified as in 3-groups, etc.,

Commutator Calculus for Wreath Product Groups
Communications in Algebra, 2015We 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.

Non-commutativity and MELL in the Calculus of Structures
2001We introduce the calculus of structures: it is more general than the sequent calculus and it allows for cut elimination and the subformula property. We show a simple extension of multiplicative linear logic, by a self-dual noncommutative operator inspired by CCS, that seems not to be expressible in the sequent calculus. Then we show that multiplicative

Commutative diagrams and tensor calculus in Riemann spaces
Il Nuovo Cimento B, 1993The 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).
