Automorphisms that commute with a modular automorphism

Letters in Mathematical Physics, 1984
For M a factor of type III1 we can find for every automorphism group γs that commutes with a modular automorphism group αt and another modular automorphism group \(\bar \alpha _t \), an automorphism group \(\bar \gamma _s \) that commutes with \(\bar \alpha _t \) is connected with γs by an inner cocycle.

Automorphism groups of Gabidulin-like codes

arXiv.org, 2016
Let K/k be a cyclic Galois extension of degree $${\ell}$$ℓ and $${\theta }$$θ a generator of Gal(K/k). For any $${v=(v_1, \ldots, v_m)\in K^{m}}$$v=(v1,…,vm)∈Km such that v is linearly independent over k, and any $${1\leq d < m }$$1 ...

Jordan property and automorphism groups of normal compact Kähler varieties

, 2017
It has been recently shown by Meng and Zhang that the full automorphism group Aut(X) is a Jordan group for all projective varieties in arbitrary dimensions.

Automorphisms of fibrations

Proceedings of the American Mathematical Society, 1980
Let X be a simplicial set, G a simplicial group and W ¯ G \bar WG the classifying complex of G. Then it is well known [1], [3] that the principal fibrations with base X and group G are classified by the components of the function complex (

Lip Automorphism Germ and Lip Automorphism [PDF]

Acta Mathematica Sinica, English Series, 2004
Let X be a metric space, e n (X) be the standard trivial Lip n-bundle over X, and φ be a Lip automorphism germ of e n (X) . This paper proves that there is a Lip automorphism φ’ of e n (X) such that the germ of φ’ is φ.

On automorphism-invariant modules

, 2015
Let M and N be two modules. M is called automorphism N-invariant if for any essential submodule A of N, any essential monomorphism f : A → M can be extended to some g ∈ Hom(N, M). M is called automorphism-invariant if M is automorphism M-invariant.

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.

K-Automorphism: A General Framework For Privacy Preserving Network Publication

Proceedings of the VLDB Endowment, 2009
The growing popularity of social networks has generated interesting data management and data mining problems. An important concern in the release of these data for study is their privacy, since social networks usually contain personal information. Simply
