Finding a feasible solution for MIP is NP-Hard and is difficult in practice for some important models and
Critical Collapse of Einstein Cluster (2007)
Mahajan, Ashutosh, Harada, Tomohiro, Joshi, Pankaj S., Nakao, Ken-ichi
We observe critical phenomena in spherically symmetric gravitational collapse of Einstein Cluster. We show analytically that the collapse evolution ends either in formation of a black hole or in...
Analytical solutions for black-hole critical behaviour (2007)
Harada, Tomohiro, Mahajan, Ashutosh
Dynamical Einstein cluster is a spherical self-gravitating system of counterrotating particles, which may expand, oscillate and collapse. This system exhibits critical behaviour in its collapse at...
n� j=1 ajxj + Substitute aj = ⌊aj ⌋ + fj, b = ⌊b ⌋ + f0. Then,
Mahajan, Ashutosh, Joshi, Pankaj S.
We examine spherical gravitational collapse of a matter model with vanishing radial pressure and non-zero tangential pressure. It is seen analytically that the collapsing cloud either forms a black...
Cosmic Censorship in Higher dimension II (2005)
Mahajan, Ashutosh, Goswami, Rituparno, Joshi, Pankaj S.
Generalizing earlier results on dust collapse in higher dimensions, we show here that cosmic censorship can be restored in gravitational collapse with tangential pressure present if we take the...
Gravitational collapse from smooth initial data with vanishing radial pressure (2003)
Mahajan, Ashutosh, Goswami, Rituparno, Joshi, Pankaj S.
We study here the spherical gravitational collapse assuming initial data to be necessarily smooth, as motivated by the requirements based on physical reasonableness. A tangential pressure model is...
