Branched holomorphic Cartan geometry on Sasakian manifolds [PDF]

open access: yesarXiv, 2018
We extend the notion of (branched) holomorphic Cartan geometry on a complex manifold to the context of Sasakian manifolds. Branched holomorphic Cartan geometries on Sasakian Calabi-Yau manifolds are investigated.

General Geometry and Geometry of Electromagnetism [PDF]

open access: yesarXiv, 2002
It is shown that Electromagnetism creates geometry different from Riemannian geometry. General geometry including Riemannian geometry as a special case is constructed. It is proven that the most simplest special case of General Geometry is geometry underlying Electromagnetism.

Abel Prize 2009 as a necessitation to discussion on geometry, or physicist versus geometers [PDF]

open access: yesarXiv, 2009
Contemporary geometers do not acknowledge nonaxomatizable geometries. This fact means that our knowledge of geometry is poor. A perfect knowledge of geometry is important for "consumers of geometry" (physicists dealing with geometry of microcosm), because poor knowledge of geometry forces physicists to refuse from the orthodox geometrical paradigm and ...

A (2+1)-dimensional integrable spin model(the M-XXII equation) and Differential geometry of curves/surfaces [PDF]

open access: yesarXiv, 1998
Using the differential geometry of curves and surfaces the Lakshmanan equivalent counterpart of the M-XXII equation is found ... .

Differential geometry of fibre bundles over foliated manifolds [PDF]

open access: yesarXiv, 2001
Any leafwise connection on a fibre bundle over a foliated manifold is proved to come from a connection on this fibre bundle.

Index theory and noncommutative geometry of topological insulator [PDF]

open access: yesarXiv, 2018
In this chapter, we report the recent progress in the understanding of the rich mathematical structures of topological insulators in the framework of index theory and noncommutative geometry.
