A survey of semisimple algebras in algebraic combinatorics [PDF]

open access: yesIndian Journal of Pure and Applied Mathematics, 2021
This is a survey of semisimple algebras of current interest in algebraic combinatorics, with a focus on questions which we feel will be new and interesting to experts in group algebras, integral representation theory, and computational algebra. The algebras arise primarily in two families: coherent algebras and subconstituent (aka.

Dynamical Algebraic Combinatorics, Asynchronous Cellular Automata, and Toggling Independent Sets

International Workshop on Cellular Automata and Discrete Complex Systems, 2021
Though iterated maps and dynamical systems are not new to combinatorics, they have enjoyed a renewed prominence over the past decade through the elevation of the subfield that has become known as dynamical algebraic combinatorics.

PARASTATISTICS ALGEBRAS AND COMBINATORICS

Mathematical, Theoretical and Phenomenological Challenges Beyond the Standard Model, 2005
We consider the algebras spanned by the creation parafermionic and parabosonic operators which give rise to generalized parastatistics Fock spaces. The basis of such a generalized Fock space can be labelled by Young tableaux which are combinatorial objects.

Combinatorics and fermion algebra

Il Nuovo Cimento B, 1973
It is shown that the various types of normal terms arising from the normal ordering of a disordered product of fermion operators can be enumerated with the aid of a well-known combinatorial problem, called the problem of the rooks.

On the Combinatorics of Free Algebras

1990
In this survey paper I discuss recent results concerning free algebraic systems and I mention some old results which motivated them. There is no attempt to be comprehensive. The selection of topics is eclectic and personal but with a special emphasis on results of a combinatorial nature.
