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.

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 ...

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.

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

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.

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.
