Canonical metrics on holomorphic fibre bundles

Bulletin of the London Mathematical Society, Volume 58, Issue 10, October 2026.
Abstract In this article, we completely describe the existence of canonical metrics, known as optimal symplectic connections, on isotrivial Kähler fibrations. In this setting an optimal symplectic connection is induced from a Hermite–Einstein connection on the holomorphic principal bundle of relative automorphisms, and the Hitchin–Kobayashi ...

Quadratic Poisson algebras on k[x, y, z]and their automorphisms

Қарағанды университетінің хабаршысы. Математика сериясы, 2016
One of the important directions in modern mathematics is applications of Poisson structures and to various problems of mathematics and theoretical mechanics. These problems arise in dynamics of a rigid body, the celestial mechanics, the theory of curls,

Derivations and automorphisms of locally matrix algebras and groups

Доповiдi Нацiональної академiї наук України
We describe derivations and automorphisms of infinite tensor products of matrix algebras. Using this description, we show that, for a countable–dimensional locally matrix algebra A over a field F, the dimension of the Lie algebra of outer derivations of ...

A Banach–Lie Approach to Ternary Symmetries in Nest Algebras

Axioms
Let N be a nest on a Banach space, and let Alg(N) denote the associated nest algebra equipped with the operator norm. In this paper, we develop a Banach–Lie framework for bounded triple derivations and triple automorphisms on Alg(N).

Construction of a group of automorphisms for an infinite family of Garside groups [PDF]

, 2014
The structure groups of non-degenerate symmetric set-theoretical solutions of the quantum Yang-Baxter equation provide an infinite family of Garside groups with many interesting properties.

Automorphisms of Spacetime Manifold with Torsion [PDF]

, 2016
summary:In this paper we prove that the maximum dimension of the Lie group of automorphisms of the Riemann–Cartan 4-dimensional manifold does not exceed 8, and if the Cartan connection is skew-symmetric or semisymmetric, the maximum dimension is equal to

A group of generalized finitary automorphisms of an abelian group

, 2017
We study the group IAut(A) generated by the inertial automorphisms of an abelian group A, that is, automorphisms f with the property that each subgroup H of A has finite index in the subgroup generated by H and f(H) .

ON THE GROUPS OF THE INFINITELY GENERATED FREE ABELIAN GROUPS AUTOMORPHISMS

Вестник Кемеровского государственного университета, 2015
Let A be an infinitely generated free abelian group. The paper shows that all automorphisms of the group Aut(A) are inner.
