Connections on non-symmetric (generalized) Riemannian manifold and gravity
, 2015 Connections with (skew-symmetric) torsion on non-symmetric Riemannian manifold satisfying the Einstein metricity condition (NGT with torsion) are considered.

Twistor spaces of generalized complex structures
, 2005 The twistor construction is applied for obtaining examples of generalized complex structures (in the sense of N. Hitchin) that are not induced by a complex or a symplectic structure.Comment: revised version, 17 pages; corrected typos, added references ...

, 2008 An analogue of the correspondence between GL(k)-conjugacy classes of matricial polynomials and line bundles is given for K-conjugacy classes, where K is one of the following: maximal parabolic, maximal torus, GL(k-1) embedded diagonally.

Twistorial construction of minimal hypersurfaces
, 2014 Every almost Hermitian structure $(g,J)$ on a four-manifold $M$ determines a hypersurface $\Sigma_J$ in the (positive) twistor space of $(M,g)$ consisting of the complex structures anti-commuting with $J$. In this note we find the conditions under which $

A double fibration transform for complex projective space
, 2016 We develop some theory of double fibration transforms where the cycle space is a smooth manifold and apply it to complex projective space.The author is supported by the Australian Research ...

Two constructions with parabolic geometries [PDF]
, 2005 This is an expanded version of a series of lectures delivered at the 25th Winter School ``Geometry and Physics'' in Srni. After a short introduction to Cartan geometries and parabolic geometries, we give a detailed description of the equivalence ...
