On horizontal and complete lifts from a manifold with fλ(7,1)-structure to its cotangent bundle

Autor: Lovejoy S. Das, Ram Nivas, Virendra Nath Pathak

Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 2005, Iss 8, Pp 1291-1297 (2005)

The horizontal and complete lifts from a manifold Mn to its cotangent bundles T∗(Mn) were studied by Yano and Ishihara, Yano and Patterson, Nivas and Gupta, Dambrowski, and many others. The purpose of this paper is to use certain methods by which f

Complete lift of a structure satisfying FK−(−)K+1F=0

Autor: Lovejoy S. Das

Publikováno v: International Journal of Mathematics and Mathematical Sciences, Vol 15, Iss 4, Pp 803-808 (1992)

The idea of f-structure manifold on a differentiable manifold was initiated and developed by Yano [1], Ishihara and Yano [2], Goldberg [3] and among others. The horizontal and complete lifts from a differentiable manifold Mn of class C∞ to its cota

On Tachibana and Vishnevskii Operators Associated with Certain Structures in the Tangent Bundle

Autor: Mohammad Nazrul Islam Khan, Lovejoy S. Das

Publikováno v: Journal of Applied Mathematics and Physics. :1968-1978

The aim of the present work is to study the complete, vertical and horizontal lifts using Tachibana and Visknnevskii operators along generalized almost r-contact structure in tangent bundle. We also prove certain theorems on Tachibana and Visknnevski

On the Integrability Conditions and Operators of the F((K + 1),(K − 1))− Structure Satisfying F K+1 + F K−1 = 0, (F 6= 0, K 1 2) on Cotangent Bundle and Tangent Bundle

Autor: Haşim Çayir, Lovejoy S. Das

International Electronic Journal of Geometry

This paper consists of two main sections. In the first part, we find the integrability conditions of the horizontal lifts of $F((K+1),(K-1))-$ structure satisfying $F^{K+1}+F^{K-1}=0,$ $(F\neq 0,$ $K\eqslantgtr 2)$. Later, we get the results of Tachi
