Simulation of advective accretion flows around black holes under various outer boundary conditions

Rajiv Kumar, Seong-Jae Lee

We simulated various accretion disc structures with viscous hydrodynamic (HD) flow around a black hole (BH). We found that the structure of the accretion disc is significantly infl…

Purity of extremal rays of Betti cones

H. Ananthnarayan, Omkar Javadekar, Rajiv Kumar

Let $R$ be a standard graded algebra over an infinite field $k$ , and let $B_{Q} (R)$ and $B_{Q}^{pure} (R)$ denote the rational c…
