Thin Shell Wormhole in Heterotic String Theory
F. Rahaman, M. Kalam, S. Chakraborti
Using 'Cut and Paste' technique, we develop a thin shell wormhole in heterotic string theory. We determine the surface stresses, which are localized in the shell, by using Darmois-…

Brane world solutions of perfect fluid in the background of a bulk containing dust or cosmological constant
Tanwi Bandyopadhyay, Subenoy Chakraborty, Asit Banerjee
The paper presents some solutions to the five dimensional Einstein equations due to a perfect fluid on the brane with pure dust filling the entire bulk in one case and a cosmologic…
