Remarks on the star product of functions on finite and compact groups [PDF]

open access: yes, 2009
Using the formalism of quantizers and dequantizers, we show that the characters of irreducible unitary representations of finite and compact groups provide kernels for star products of complex-valued functions of the group elements.

⁎-freeness in finite tensor products

open access: yesAdvances in Applied Mathematics, 2017
In this paper, we consider the following question and variants thereof: given $\mathbf D:=\big(a_{1;i}\otimes\cdots\otimes a_{K;i}:i\in I\big)$, a collection of elementary tensor non-commutative random variables in the tensor product of probability spaces $(\mathcal A_1\otimes\cdots\otimes\mathcal A_K, _1\otimes\cdots\otimes _K)$, when is $\mathbf D$

Automaton semigroups: new construction results and examples of non-automaton semigroups [PDF]

open access: yes, 2017
This paper studies the class of automaton semigroups from two perspectives: closure under constructions, and examples of semigroups that are not automaton semigroups.

Finite products of limits of direct systems induced by maps

open access: yesApplied General Topology, 2015
Let Z, H be spaces. In previous work, we introduced the direct (inclusion) system induced by the set of maps between the spaces Z and H. Its direct limit is a subset of Z × H, but its topology is different from the relative topology.

Factorization in Phase-Space Finite Geometry and Weak Mutually Unbiased Bases

open access: yesAfrican Scientific Reports, 2023
A phase-space factorization of lines in finite geometry G(m) with variables in Zm and its correspondence in finite Hilbert space H(m) for m a non-prime was discussed. Using the method of Good [15], lines in G(m) were factorized as products of lines G(mi)

Planning complex engineer-to-order products [PDF]

open access: yes, 2003
The design and manufacture of complex Engineer-to-Order products is characterised by uncertain operation durations, finite capacity resources and multilevel product structures.

On the Connection between Kronecker and Hadamard Convolution Products of Matrices and Some Applications

open access: yesJournal of Inequalities and Applications, 2009
We are concerned with Kronecker and Hadamard convolution products and present some important connections between these two products. Further we establish some attractive inequalities for Hadamard convolution product.

Nonsolvable Groups Whose Degrees of All Proper Subgroups Are the Direct Products of at Most Two Prime Numbers

open access: yesJournal of Mathematics, 2022
Huppert and Manz have determined the nonsolvable groups whose character degrees are products of at most two prime numbers. In this paper, we change the condition from “degrees of a group are products of at most two prime divisors” to “degrees of all ...

Infinite products of finite simple groups [PDF]

open access: yesTransactions of the American Mathematical Society, 1996
We classify the sequences ⟨ S n ∣ n ∈ N ⟩ \langle S_{n} \mid n \in \mathbb {N} \rangle of finite simple nonabelian groups such that ∏ n S

Faithful group actions and Schreier graphs

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2018
Each action of a finitely generated group on a set uniquely defines a labelled directed graph called the Schreier graph of the action. Schreier graphs are used mainly as a tool to establish geometrical and dynamical properties of corresponding group ...
