Journal of High Energy Physics, 2022 The conformal algebra in 2D (Diff(S 1)⨁Diff(S 1)) is shown to be preserved under a nonlinear map that mixes both chiral (holomorphic) generators T and T ¯ $$ \overline{T} $$ .

Graphical models for topological groups: A case study on countable Stone spaces
Bulletin of the London Mathematical Society, EarlyView.Abstract By analogy with the Cayley graph of a group with respect to a finite generating set or the Cayley–Abels graph of a totally disconnected, locally compact group, we detail countable connected graphs associated to Polish groups that we term Cayley–Abels–Rosendal graphs.

Centralizers of automorphisms permuting free generators
Open Mathematics, 2019 By σ ∈ Skm we denote a permutation of the cycle-type km and also the induced automorphism permuting subscripts of free generators in the free group Fkm.

On structure of isomorphisms of universal graphic automata [PDF]
Известия Саратовского университета. Новая серия. Серия Математика. Механика. ИнформатикаAutomata theory is one of the branches of mathematical cybernetics, that studies information transducers that arise in many applied problems. The major objective of automata theory is to develop methods by which one can describe and analyze the dynamic ...

Thurston obstructions and tropical geometry
Bulletin of the London Mathematical Society, EarlyView.Abstract We describe an application of tropical moduli spaces to complex dynamics. A post‐critically finite branched covering φ$\varphi$ of S2$S^2$ induces a pullback map on the Teichmüller space of complex structures of S2$S^2$; this descends to an algebraic correspondence on the moduli space of point‐configurations of P1$\mathbb {P}^1$.

Automorphisms of central extensions of type I von Neumann algebras
, 2011 Given a von Neumann algebra $M$ we consider the central extension $E(M)$ of $M.$ For type I von Neumann algebras $E(M)$ coincides with the algebra $LS(M)$ of all locally measurable operators affiliated with $M.$ In this case we show that an arbitrary ...

On the maximum Graovac-Pisanski index of bicyclic graphs
AIMS Mathematics, 2023 For a simple graph $ G = (V(G), E(G)) $, the Graovac-Pisanski index of $ G $ is defined as $ GP(G) = \frac{|V(G)|}{2|{\rm{Aut}}(G)|}\sum\limits_{u\in V(G)}\sum\limits_{\alpha\in {\rm{Aut}}(G)}d_G(u,\alpha(u)), $ where $ {\rm{Aut}}(G) $ is the ...

Wild blocks of type A$A$ Hecke algebras are strictly wild
Bulletin of the London Mathematical Society, EarlyView.Abstract We prove that all wild blocks of type A$A$ Hecke algebras with quantum characteristic e⩾3$e \geqslant 3$ — that is, blocks of weight at least 2 — are strictly wild, with the possible exception of the weight 2 Rouquier block for e=3$e = 3$.

An identity involving automorphisms of prime rings inspired by Posner's theorem
Journal of Taibah University for Science, 2018 Let ${\mathcal R}$ be a prime ring with centre ${\mathcal Z}(\mathcal {R})$, $\mathcal {L}$ a non-zero Lie ideal of ${\mathcal R}$, and σ a non-trivial automorphism of ${\mathcal R}$ such that $[[\sigma (u),u], \sigma (u)] \in \mathcal {Z}(\mathcal {R})$
