Automorphism group of the complete transposition graph

, 2014
The complete transposition graph is defined to be the graph whose vertices are the elements of the symmetric group $$S_n$$Sn, and two vertices $$\alpha $$α and $$\beta $$β are adjacent in this graph iff there is some transposition (i, j) such that ...

The Automorphism Group of the Hilbert Scheme of Two Points on a Generic Projective K3 Surface

, 2014
We determine the automorphism group of the Hilbert scheme of two points on a generic projective K3 surface of any polarization. We obtain in particular new examples of Hilbert schemes of points having non-natural non-symplectic automorphisms.

The Automorphism Group of a Lie Group

Transactions of the American Mathematical Society, 1952
Introduction. The group A (G) of all continuous and open automorphisms of a locally compact topological group G may be regarded as a topological group, the topology being defined in the usual fashion from the compact and the open subsets of G (see ?1). In general, this topological structure of A (G) is somewhat pathological.

Hyperimaginaries and automorphism groups

Journal of Symbolic Logic, 2001
A hyperimaginary is an equivalence class of a type-definable equivalence relation on tuples of possibly infinite length. The notion was recently introduced in [1], mainly with reference to simple theories. It was pointed out there how hyperimaginaries still remain in a sense within the domain of first order logic.

Noetherian Automorphisms of Groups

Mediterranean Journal of Mathematics, 2005
An automorphism α of a group G is called a noetherian automorphism if for each ascending chain $$ X_1 < X_2 < \ldots < X_n < X_{n + 1} < \ldots $$ of subgroups of G there is a positive integer m such that \(X_n^{\alpha} = X_n \) for all n ≥ m. The structure of the group of all noetherian automorphisms of a group is investigated in this paper.

Automorphism groups of pictures

Journal of Graph Theory, 1990
AbstractA picture is a simple graph together with an edge‐coloring, such that each vertex is incident with exactly one edge of each color. An automorphism of a picture is a graph automorphism that preserves the colors of the edges. We show that every group is isomorphic to the full automorphism group of a picture, and prove that a group is isomorphic ...

On the automorphisms of the Cremona group.

2006
In the recent paper [\textit{J. Déserti}, J. Algebra 297, No.~2, 584--599 (2006; Zbl 1096.14046)] the author has established that, over an uncountable field \(k\) of characteristic 0, the automorphism group of the group of algebraic automorphisms \(\text{Aut}(k^2)\) of the affine plane is generated by the inner automorphisms of \(\text{Aut}(k^2)\) and ...
