Polynomial Mappings with Small Degree

open access: yesDemonstratio Mathematica, 2015
Let Xn be an affine variety of dimension n and Yn be a quasi-projective variety of the same dimension. We prove that for a quasi-finite polynomial mapping ƒ : Xn → Yn, every non-empty component of the set Yn\ ƒ (Xn) is closed and it has dimension greater

AV-differential geometry and Newtonian mechanics [PDF]

open access: yes, 2006
A frame independent formulation of analytical mechanics in the Newtonian space-time is presented The differential geometry of affine values i.e., the differential geometry in which affine bundles replace vector bundles and sections of one dimensional ...

R-convexity in R-vector spaces

open access: yesJournal of Inequalities and Applications, 2022
In this paper, for every relation R on a vector space V, we consider the R-vector space ( V , R ) $(V,R)$ and define the notions of R-convexity, R-convex hull, and R-extreme point in this space.

Preserving affine Baire classes by perfect affine maps

open access: yes, 2015
Let $\varphi\colon X\to Y$ be an affine continuous surjection between compact convex sets. Suppose that the canonical copy of the space of real-valued affine continuous functions on $Y$ in the space of real-valued affine continuous functions on $X$ is ...

On Affine Symmetric Spaces [PDF]

open access: yesTransactions of the American Mathematical Society, 1965
the connected component of identity in G . Conversely, if G is a Lie group with an involutive automorphism E and H is a subgroup satisfying Go a H c GE, then H is a closed subgroup of G and the coset space G/H is an analytic manifold; furthermore, the canonical invariant affine connection of G induces an affine connection on M = G / H, which renders M ...

On affine motions with one-dimensional orbits in common spaces of paths

open access: yesДифференциальная геометрия многообразий фигур
The concept of a common path space was introduced by J. Duqlas. M. S. Knebelman was the first to consider affine and projective move­ments in these spaces. The general path space is a generalization of the space of affine connectivity.

The decomposition and classification of radiant affine 3-manifolds

open access: yes, 2000
An affine manifold is a manifold with torsion-free flat affine connection. A geometric topologist's definition of an affine manifold is a manifold with an atlas of charts to the affine space with affine transition functions; a radiant affine manifold is ...

Moduli Spaces of Affine Homogeneous Spaces [PDF]

open access: yesBulletin of the Belgian Mathematical Society - Simon Stevin, 2019
Apart from global topological problems an affine homogeneous space is locally described by its curvature, its torsion and a slightly less tangible object called its connection in a given base point. Using this description of the local geometry of an affine homogeneous space we construct an algebraic variety $\mathfrak{M}(\mathfrak{gl}\,V)$, which ...

open access: yes, 2014
Drinfeld Zastava is a certain closure of the moduli space of maps from the projective line to the Kashiwara flag scheme of the affine Lie algebra $\hat{sl}_n$.
