Higher Lovelock Curvature Terms Favor Local Nakedness in Dust Collapse
Apratim Ganguly, Radouane Gannouji, Akshay Kumar
We show that higher-curvature Lovelock terms do not restore local cosmic censorship in spherical dust collapse, but instead promote the local visibility of central shell-focusing s…

Spherical trapped surfaces in n-dimensional general relativity
Ayan Chatterjee, Suresh C. Jaryal, Akshay Kumar
In this paper, we examine gravitational collapse of matter fields in -dimensional general relativity. The matter energy-momentum tensor under consideration includes dust, perfec…

Gravitational collapse in pure Gauss- Bonnet theory
Akshay Kumar, Ayan Chatterjee, Suresh C. Jaryal
In this paper, we study the gravitational collapse of matter fields, which include dust, perfect fluids as well as fluids admitting bulk and shear viscosity. The initial conditions…
