An Analytical Study on the Multi-critical Behaviour and Related Bifurcation Phenomena for Relativistic Black Hole Accretion
Shilpi Agarwal, Tapas K. Das, Rukmini Dey +1
We apply the theory of algebraic polynomials to analytically study the transonic properties of general relativistic hydrodynamic axisymmetric accretion onto non-rotating astrophysi…

Transonicity in black hole accretion -- A mathematical study using the generalized Sturm chains
Shilpi Agarwal, Tapas K. Das, Rukmini Dey
By applying the theory of algebraic polynomials and the theory of dynamical systems, we construct the generalized Sturm sequences/chains to investigate the transonic properties of…
