The Existence of Cartan Connections and Geometrizable Principal Bundles [PDF]

open access: yes, 2004
The aim of this article is to proof a necessary and sufficient condition for the existence of a Cartan connection on a principal bundle. After collecting the essentially well known facts to fix the terminology, soldering forms and geometrizable principal

Сurvature-torsion tensor for Cartan connection

open access: yesДифференциальная геометрия многообразий фигур, 2019
A Lie group containing a subgroup is considered. Such a group is a principal bundle, a typical fiber of this principal bundle is the subgroup and a base is a homogeneous space, which is obtained by factoring the group by the subgroup.

Induced connections of two types on a surface of an affine space

open access: yesДифференциальная геометрия многообразий фигур, 2019
In the affine space the fundamental-group connection in the bundle associated with a surface as a manifold of tangent planes is investigated. The principal bundle contains a quotient bundle of tangent frames, the typical fiber of which is a linear group ...

Nonabelian Bundle Gerbes, their Differential Geometry and Gauge Theory [PDF]

open access: yes, 2003
Bundle gerbes are a higher version of line bundles, we present nonabelian bundle gerbes as a higher version of principal bundles. Connection, curving, curvature and gauge transformations are studied both in a global coordinate independent formalism and ...

he deformation pseudotensor of connections in cocongruence K (n - m)m

open access: yesДифференциальная геометрия многообразий фигур, 2023
The Grassmann manifold is the set of all -dimensional planes of an -dimensional projective space, with dim. One of the submanifolds of the Grassmann manifold is a complex of -planes if the dimension of the complex exceeds the difference .

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.

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.

Connections on locally trivial quantum principal fibre bundles

open access: yes, 2000
Following the approach of Budzy\'nski and Kondracki, we define covariant differential algebras and connections on locally trivial quantum principal fibre bundles.

Non-abelian higher gauge theory and categorical bundle

open access: yes, 2016
A gauge theory is associated with a principal bundle endowed with a connection permitting to define horizontal lifts of paths. The horizontal lifts of surfaces cannot be defined into a principal bundle structure.
