The effect of short ray trajectories on the scattering statistics of wave chaotic systems

, 2009
In many situations, the statistical properties of wave systems with chaotic classical limits are well-described by random matrix theory. However, applications of random matrix theory to scattering problems require introduction of system specific ...

Gauge conditions for binary black hole puncture data based on an approximate helical Killing vector

, 2003
We show that puncture data for quasicircular binary black hole orbits allow a special gauge choice that realizes some of the necessary conditions for the existence of an approximate helical Killing vector field.

An Effective Ratner Equidistribution Result for ASL(2,R)

, 2014
Let G=ASL(2,R) be the affine special linear group of the plane, and set Gamma=ASL(2,Z). We prove a polynomially effective asymptotic equidistribution result for the orbits of a 1-dimensional, non-horospherical unipotent flow on Gamma\G.Comment: A few ...

Computing (Un)stable Manifolds with Validated Error Bounds: Non-resonant and Resonant Spectra

Journal of nonlinear science, 2016
We develop techniques for computing the (un)stable manifold at a hyperbolic equilibrium of an analytic vector field. Our approach is based on the so-called parametrization method for invariant manifolds.
