Curvatures in contravariant warped product space
P. Kumar, B. Pal, S. Kumar
In this article, we introduce the sectional curvature in contravariant warped product space , where ). After that we find…
Characterization of Einstein Poisson warped product space
B. Pal, P. Kumar
In this article, we study the problem of the existence and nonexistence of warping function associated with constant scalar curvature on pseudo-Riemannian Poisson warped product sp…
Some characterizations of rectifying curves on a smooth surface in Euclidean 3-space
Akhilesh Yadav, Buddhadev Pal
In this paper, we investigate sufficient condition for the invariance of a rectifying curve on a smooth surface immersed in Euclidean 3-space under isometry by using Darboux frame…
Darboux Rectifying curves on a smooth surface
Buddhadev Pal, Akhilesh Yadav
The main aim of this paper is to investigate Darboux rectifying curves on a smooth surface immersed in the Euclidean space. First, we discuss the component of the position vector o…
