LargeScale Simulations of Reionization
 ApJ
, 2007
"... We use cosmological simulations to explore the largescale effects of reionization. Since reionization is a process that involves a large dynamic range from galaxies to rare bright quasars we need to be able to cover a significant volume of the universe in our simulation without losing the importa ..."

This lecture addresses numerical solutions of differential equations with random inputs. The source of random inputs includes uncertainty in system parameters, boundary and initial conditions, material properties, source and interaction terms, random roughness, etc. Such types of uncertainty are encountered often in applications, and are typically modeled as random fields. The classical approach is to model the random inputs as functionals of idealized processes such as Wiener processes, Poisson processes, etc. This approach has led to elegant mathematical analysis and corresponding numerical methods by using stochastic calculi, as e.g., Ito or Stratonovich calculus for ordinary differential equations and the stochastic calculus of variations of Malliavin for partial differential equations. The resulting differential equations are broadly termed “stochastic ordinary/partial differential equations. Recently, more research efforts have been devoted to studying problems with more realistic random inputs, e.g., correlated random processes and, in case of random parameters, fully correlated random processes, i.e., random variables. In this context, the classical stochastic calculi does not readily apply and hence other approaches are
