Finite sampling interval effects in Kramers-Moyal analysis

open access: yes, 2009
Large sampling intervals can affect reconstruction of Kramers-Moyal coefficients from data. A new method, which is direct, non-stochastic and exact up to numerical accuracy, can estimate these finite-time effects.

Perturbative Solutions of the Extended Constraint Equations in General Relativity

open access: yes, 2006
The extended constraint equations arise as a special case of the conformal constraint equations that are satisfied by an initial data hypersurface $Z$ in an asymptotically simple spacetime satisfying the vacuum conformal Einstein equations developed by H.
