Beyond-Newtonian dynamics of a planar circular restricted three-body problem with Kerr-like primaries

Shounak De, Suparna Roychowdhury, Roopkatha Banerjee

The dynamics of the planar circular restricted three-body problem with Kerr-like primaries in the context of a beyond-Newtonian approximation is studied. The beyond-Newtonian poten…

Bounds on Dark Matter Annihilation Cross-sections from Inert Doublet Model in the context of 21 cm Cosmology of Dark Ages

Rupa Basu, Madhurima Pandey, Debasish Majumdar +1

We study the fluctuations in the brightness temperature of 21-cm signal $δ T_{21}$ at the dark ages ( $z \sim 100$ ) with a dark matter candidate in Inter Doublet Model (IDM). We then e…

On Generalization of $δ$ -Primary Elements in Multiplicative Lattices

A. V. Bingi

In this paper, we introduce $ϕ$ - $δ$ -primary elements in a compactly generated multiplicative lattice $L$ and obtain its characterizations. We prove many of its properties and inves…
