Future stability of self-gravitating dust balls in an expanding universe
Shabnam Beheshti, Mikael Normann, Juan Valiente Kroon
We consider a system representing self-gravitating balls of dust in an expanding Universe. It is demonstrated that one can prescribe data for such a system at infinity and evolve i…
Marginally stable circular orbits in stationary axisymmetric spacetimes
Shabnam Beheshti, Edgar Gasperin
We derive a necessary condition for the existence of marginally stable circular orbits of test particles in stationary axisymmetric spacetimes which possess a refection symmetry wi…
Dressing with Control: using integrability to generate desired solutions to Einstein's equations
Shabnam Beheshti, A. Shadi Tahvildar-Zadeh
Motivated by integrability of the sine-Gordon equation, we investigate a technique for constructing desired solutions to Einstein's equations by combining a dressing technique with…
Remarks on Combinatorial Aspects of the KP Equation
Shabnam Beheshti, Amanda Redlich
We survey several results connecting combinatorics and Wronskian solutions of the KP equation, contextualizing the successes of a recent approach introduced by Kodama, et. al. We i…
Integrability and Vesture for Harmonic Maps into Symmetric Spaces
Shabnam Beheshti, A. Shadi Tahvildar-Zadeh
After giving the most general formulation to date of the notion of integrability for axially symmetric harmonic maps from R^3 into symmetric spaces, we give a complete and rigorous…
On Generalized Monopole Spherical Harmonics and the Wave Equation of a Charged Massive Kerr Black Hole
Shabnam Beheshti, Floyd L. Williams
We find linearly independent solutions of the Goncharov-Firsova equation in the case of a massive complex scalar field on a Kerr black hole. The solutions generalize, in some sense…
