Weyl-ambient geometries

open access: yesNuclear Physics B, 2023
Weyl geometry is a natural extension of conformal geometry with Weyl covariance mediated by a Weyl connection. We generalize the Fefferman-Graham (FG) ambient construction for conformal manifolds to a corresponding construction for Weyl manifolds.

Gauge and Gravity theories on a dynamical principal bundle [PDF]

open access: yes, 2023
In this paper we present original variational formulations of Yang-Mills, Einstein's gravitation and Kaluza-Klein theories, where, in the spirit of General Relativity, the principal bundle structure over the space-time is not fixed a priori but is ...

Exotic spheres’ metrics and solutions via Kaluza-Klein techniques

open access: yesJournal of High Energy Physics, 2023
By applying an inverse Kaluza-Klein procedure, we provide explicit coordinate expressions for Riemannian metrics on two homeomorphic but not diffeomorphic spheres in seven dimensions.

Equivariant principal bundles for G–actions and G–connections

open access: yesComplex Manifolds, 2015
Given a complex manifold M equipped with an action of a group G, and a holomorphic principal H–bundle EH on M, we introduce the notion of a connection on EH along the action of G, which is called a G–connection.

Curvature-torsion quasitensor of Laptev fundamental-group connection

open access: yesДифференциальная геометрия многообразий фигур, 2020
We consider a space with Laptev's fundamental group connection generalizing spaces with Cartan connections. Laptev structural equations are reduced to a simpler form.

Affine Connection Representation of Gauge Fields

open access: yesAdvances in High Energy Physics, 2022
There are two ways to unify gravitational field and gauge field. One is to represent gravitational field as principal bundle connection, and the other is to represent gauge field as affine connection.

Geometry of frame bundles

open access: yesLietuvos Matematikos Rinkinys
In this article we define the canonical forms on the principal bundle of holonomic frames of order r, give structure equations for these forms and determine the connection of order r.

Criterion for connections on principal bundles over a pointed Riemann surface

open access: yesComplex Manifolds, 2017
We investigate connections, and more generally logarithmic connections, on holomorphic principal bundles over a compact connected Riemann surface.

Theory of Connections on Graded Principal Bundles [PDF]

open access: yesReviews in Mathematical Physics, 1998
The geometry of graded principal bundles is discussed in the framework of graded manifold theory of Kostant–Berezin–Leites. We first review the basic elements of this theory establishing at the same time supplementary properties of graded Lie groups and their actions.
