Contact Geometry of Curves [PDF]

open access: yesSymmetry, Integrability and Geometry: Methods and Applications, 2009
Cartan's method of moving frames is briefly recalled in the context of immersed curves in the homogeneous space of a Lie group $G$. The contact geometry of curves in low dimensional equi-affine geometry is then made explicit.

Non-reductive spaces with equiaffine connections of nonzero curvature [PDF]

open access: yesИзвестия Саратовского университета. Новая серия: Математика. Механика. Информатика, 2021
The introduction of this article states the object of our investigation which is structures on homogeneous spaces. The problem of establishing links between the curvature and the structure of a manifold is one of the important problems of geometry.

Lie algebras of differentiations of linear algebras over a field

open access: yesДифференциальная геометрия многообразий фигур, 2021
In this paper, we study a system of linear equations that define the Lie algebra of differentiations DerA of an arbitrary finite-dimensional linear algebra over a field.

Yang-Mills Flow and Uniformization Theorems [PDF]

open access: yes, 1997
We consider a parabolic-like systems of differential equations involving geometrical quantities to examine uniformization theorems for two- and three-dimensional closed orientable manifolds.

Exterior differential systems, Lie algebra cohomology, and the rigidity of homogenous varieties [PDF]

open access: yes, 1981
These are expository notes from the 2008 Srni Winter School. They have two purposes: (1) to give a quick introduction to exterior differential systems (EDS), which is a collection of techniques for determining local existence to systems of partial ...

Balanced Metric and Berezin Quantization on the Siegel-Jacobi Ball [PDF]

open access: yes, 2016
We determine the matrix of the balanced metric of the Siegel-Jacobi ball and its inverse. We calculate the scalar curvature, the Ricci form and the Laplace-Beltrami operator of this manifold.

Holomorphic Parabolic Geometries and Calabi-Yau Manifolds [PDF]

open access: yes, 2011
We prove that the only complex parabolic geometries on Calabi-Yau manifolds are the homogeneous geometries on complex tori.

Invariant Forms and Automorphisms of Locally Homogeneous Multisymplectic Manifolds

open access: yes, 2012
It is shown that the geometry of locally homogeneous multisymplectic manifolds (that is, smooth manifolds equipped with a closed nondegenerate form of degree > 1, which is locally homogeneous of degree k with respect to a local Euler field) is ...

On post-Lie algebras, Lie--Butcher series and moving frames

open access: yes, 2013
Pre-Lie (or Vinberg) algebras arise from flat and torsion-free connections on differential manifolds. They have been studied extensively in recent years, both from algebraic operadic points of view and through numerous applications in numerical analysis,

Privileged Coordinates and Nilpotent Approximation of Carnot Manifolds, I. General Results

open access: yes, 2018
In this paper we attempt to give a systematic account on privileged coordinates and the nilpotent approximation of Carnot manifolds. By a Carnot manifold it is meant a manifold with a distinguished filtration of subbundles of the tangent bundle which is ...
