Shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional manifold and their classification [PDF]
ریاضی و جامعهThis paper aims to study of shape operator of an $ (n-1) $-dimensional distribution on an $ n $-dimensional smooth manifold. In this study firstly we state formulae for the shape operator and its symmetric and anti-symmetric components and in ...

On Fundamental Formulas of Foliations. [PDF]
, 1999 In recent years, there have been several studies of foliations from differential geometric aspects. Especially, many differential geometric properties of metric foliations have been studied.

Connectivity of the space of ending laminations [PDF]
, 2009 We prove that for any closed surface of genus at least four, and any punctured surface of genus at least two, the space of ending laminations is connected. A theorem of E.

Geometric Structures and Substructures on Uniruled Projective Manifolds
, 2016 In a series of works on uniruled projective manifolds starting in the late 1990’s, Jun-Muk Hwang and the author have developed the basics of a geometric theory of uniruled projective manifolds arising from the study of varieties of minimal rational ...

The Representation of Time and Change in Mechanics [PDF]
, 2005 This paper is concerned with the representation of time and change in classical (i.e., non-quantum) physical theories. One of the main goals is to attempt to clarify the nature and scope of the so-called problem of time: a knot of technical and ...

Dust, Time, and Symmetry [PDF]
, 2004 Two symmetry arguments are discussed, each purporting to show that there is no more room in general relativistic cosmology than in Minkowski spacetime for a preferred division of spacetime into instants of time.

Spinors, embeddings and gravity
, 1988 This thesis is concerned with the theory of spinors, embeddings and everywhere invariance with applications to general relativity. The approach is entirely geometric with particular emphasis on the use of natural structures.
