On holomorphically projective mappings of parabolic K\"ahler manifolds

open access: yes, 2017
In this paper we study fundamental equations of holomorphically projective mappings of parabolic Kähler spaces (which are generalized classical, pseudoand hyperbolic Kähler spaces) with respect to the smoothness class of metrics.

On the mobility degree of (pseudo-) Riemannian spaces with respect to concircular mappings

open access: yes, 2013
In this paper we study the mobility degree of (pseudo-) Riemannian spaces with respect to concircular mappings. We assume that the smoothness class of differentiability is C .

Parallelizations on products of spheres and octonionic geometry

open access: yesComplex Manifolds, 2019
A classical theoremof Kervaire states that products of spheres are parallelizable if and only if at least one of the factors has odd dimension. Two explicit parallelizations on Sm × S2h−1 seem to be quite natural, and have been previously studied by the ...

Complex quaternionic manifolds and C-projective structures

open access: yesComplex Manifolds
We discuss complex quaternionic manifolds, i.e., those that have holonomy GL(n,H)U(1) $GL\left(n,\mathbb{H}\right)U\left(1\right)$ , which naturally arise via quaternionic Feix–Kaledin construction.
