Traversable wormhole models in gravity
B. Mishra, A. S. Agrawal, S. K. Tripathy +1
In this work, we analyze the wormhole solutions in gravity. Specifically we sought for wormhole geometry solutions for the following three shape functions: (i) $b(r)=r_{0}+ρ…
Cosmological model with time varying deceleration parameter in gravity
