Tolman IV fluid sphere in bigravity
Ksh. Newton Singh, Susmita Sarkar, Farook Rahaman
We present Tolman IV spacetime representing compact fluid sphere in bigravity. Here we have explored the effect of scale parameter in the local matter distribution of compact s…
Possible formation of wormholes from dark matter in an isothermal galactic halo and void
Nayan Sarkar, Susmita Sarkar, Farook Rahaman +2
It is well known that traversable wormholes are valid solutions of the Einstein field equations, but these structures can only be maintained by violating the null energy condition.…
Study of memory effect in an EOQ model for completely backlogged demand during shortage
Rituparna Pakhira, Uttam Ghosh, Susmita Sarkar +1
The most commonly developed inventory models are the classical economic order quantity model, is governed by the integer order differential equations. We want to come out from the…
Generating functions of wormholes
Farook Rahaman, Susmita Sarkar, Ksh. Newton Singh +1
It is known that wormhole geometry could be found solving the Einstein field equations by tolerating the violation of null energy condition (NEC). Violation of NEC is not possible…
Black holes/naked singularities in four-dimensional non-static space-time and the energy-momentum distributions
Faizuddin Ahmed, Farook Rahaman, Susmita Sarkar
In this article, we discuss four dimensional non-static space-times in the background of de-Sitter and anti-de Sitter spaces with the matter-energy sources a stiff fluid, anisotrop…
Qualitative Analysis and Optimal Control Strategy of an SIR Model with Saturated Incidence and Treatment
Jayanta Kumar Ghosh, Uttam Ghosh, M. H. A. Biswas +1
This paper deals with an SIR model with saturated incidence rate affected by inhibitory effect and saturated treatment function. Two control functions have been used, one for vacci…
