On central endomorphisms of a group [PDF]
International Journal of Group Theory, 2015 Let Γ be a normal subgroup of the full automorphism group Aut(G) of a group G , and assume that Inn(G)≤Γ . An endomorphism σ of G is said to be {\it Γ -central} if σ induces the the identity on the factor group G/C G (Γ) .

The diagonal dimension of sub‐C∗$\mathrm{C}^*$‐algebras
Proceedings of the London Mathematical Society, Volume 133, Issue 4, October 2026.Abstract We introduce diagonal dimension, a version of nuclear dimension for diagonal sub-C∗$\text{sub-}\mathrm{C}^*$‐algebras (sometimes also referred to as diagonal C∗$\mathrm{C}^*$‐pairs). Our concept has good permanence properties and detects more refined information than nuclear dimension.

The automorphism group of the quantum grassmannian [PDF]
The automorphism group of a quantised coordinate algebra is usually much smaller than that of its classical counterpart. Nevertheless, these automorphism groups are often very difficult to calculate.

Bounded Automorphisms of Groups
Journal of Algebra, 1994 Let \(G\) be the fundamental group of a graph of groups (in the sense of Bass-Serre theory). Such a group has a natural length function and thus a corresponding notion of bounded subgroups and bounded automorphisms. The general result of this paper is that an automorphism of \(G\) is bounded if and only if it is induced by isomorphisms of vertex groups

Ree groups as automorphism groups of block designs
Examples and CounterexamplesA recent classification of flag-transitive 2-designs with parameters (v,k,λ) whose replication number r is coprime to λ gives rise to eight possible infinite families of 2-designs, some of which are with new parameters.

Finite Quotients of the Automorphism Group of a Free Group
, 1977 Let G and F be groups. A G-defining subgroup of F is a normal subgroup N of F such that F/N is isomorphic to G. The automorphism group Aut (F) acts on the set of G-defining subgroups of F.

Steiner triple systems of order 19 with nontrivial automorphism group
, 1992 There are 172,248 Steiner triple systems of order 19 having a nontrivial automorphism group. Computational methods suitable for generating these designs are developed.

Flux Landscape with enhanced symmetry not on SL(2, ℤ) elliptic points
Journal of High Energy PhysicsWe study structures of solutions for SUSY Minkowski F-term equations on two toroidal orientifolds with h 2,1 = 1. Following our previous study [1], with fixed upper bounds of a flux D3-brane charge N flux, we obtain a whole Landscape and a distribution ...

The automorphism group of a finite metacyclic 𝑝-group
, 1970 In this paper it is shown that if G G is a finite non-Abelian metacyclic p p -group, p ≠ 2 p \ne 2 , then the order of G G divides the order of the automorphism
