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…
Particle motion around charged black holes in generalized dilaton-axion gravity
Susmita Sarkar, Farook Rahaman, Irina Radinschi +2
The behaviour of massive and massless test particles around asymptotically flat and spherically symmetric, charged black holes in the context of generalized dilaton-axion gravity i…
