Invariance of KMS states on graph C*-algebras under classical and quantum symmetry

open access: yes, 2018
We study invariance of KMS states on graph C*-algebras coming from strongly connected and circulant graphs under the classical and quantum symmetry of the graphs.

Automorphisms of the Nottingham Group

open access: yesJournal of Algebra, 2000
AbstractLet K be a finite field of characteristic p≥5. The Nottingham group N over K is the group of normalised automorphisms of the local field K((t)). In this paper we determine the automorphism group of N; in particular we show that every automorphism of the Nottingham group is standard.

New example of strongly regular graph with parameters (81,30,9,12) and a simple group A5 as the automorphism group

open access: yesExamples and Counterexamples, 2023
A new strongly regular graph with parameters (81,30,9,12) is found as a graph invariant under certain subgroup of the full automorphism group of the previously known strongly regular graph discovered in 1981 by J. H. van Lint and A. Schrijver.

More on the Schur group of a commutative ring

open access: yesInternational Journal of Mathematics and Mathematical Sciences, 1985
The Schur group of a commutative ring, R, with identity consists of all classes in the Brauer group of R which contain a homomorphic image of a group ring RG for some finite group G.
