$G$-Connections on principal bundles over complete $G$-varieties [PDF]

open access: greenJournal of Pure and Applied Algebra
Let $X$ be a complete variety over an algebraically closed field $k$ of characteristic zero, equipped with an action of an algebraic group $G$. Let $H$ be a reductive group. We study the notion of $G$-connection on a principal $H$-bundle. We give necessary and sufficient criteria for the existence of $G$-connections extending the Atiyah-Weil type ...

Criterion for connections on principal bundles over a pointed Riemann surface

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

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.

A geometric approach to discrete connections on principal bundles

open access: bronzeJournal of Geometric Mechanics, 2013
This work revisits, from a geometric perspective, the notion of discrete connection on a principal bundle, introduced by M. Leok, J. Marsden and A. Weinstein. It provides precise definitions of discrete connection, discrete connection form and discrete horizontal lift and studies some of their basic properties and relationships. An existence result for

Logarithmic Connections on Principal Bundles and Their Applications to Geometric Control Theory

open access: goldAxioms
In this research, we establish a precise correspondence between the theory of logarithmic connections on principal G-bundles over compact Riemann surfaces and the geometric formulation of control systems on curved manifolds, providing a novel ...

Linear and projective connections over a smooth manifold

open access: yesДифференциальная геометрия многообразий фигур, 2023
The principal bundles of the first order coframes and the second order coframes, as well as factor bundle of centroprojective (coaffine) coframes are considered.

Can You Hear the Shape of a Market? Geometric Arbitrage and Spectral Theory

open access: yesAxioms, 2021
Utilizing gauge symmetries, the Geometric Arbitrage Theory reformulates any asset model, allowing for arbitrage by means of a stochastic principal fibre bundle with a connection whose curvature measures the “instantaneous arbitrage capability”.

Curvature and torsion pseudotensors of coaffine connection in tangent bundle of hypercentred planes manifold

open access: yesДифференциальная геометрия многообразий фигур, 2020
The hypercentered planes family, whose dimension coincides with dimension of generating plane, is considered in the projective space. Two principal fiber bundles arise over it.
