Data Dependence for Ishikawa Iteration When Dealing with Contractive-Like Operators
Abstract We prove a convergence result and a data dependence for Ishikawa iteration when applied to contraction-like operators. An example…

Ergodic simulations of diffusion in random velocity fields
AbstractErgodic simulations aim at estimating ensemble average characteristics of diffusion in random fields from space averages. The traditional approach, based…
On the multi-decadal oscillation of Atlantic tropical storm activity
AbstractLong term Atlantic tropical storm activity is described by the time series of the yearly Accumulated Cyclone Energy (ACE) Index…
Itô equation model for dispersion of solutes in heterogeneous media
AbstractTransport processes in heterogeneous media such as ionized plasmas, natural porous media, and turbulent atmosphere are often modeled as diffusion…
Accurate numerical solutions to stationary free surface problems from capillarity
AbstractThe paper considers two static problems from capillarity. The first one consists in the determination of the surface of a…
Memory effects induced by dependence on initial conditions and ergodicity of transport in heterogeneous media
AbstractFor transport in statistically homogeneous random velocity fields with properties that are routinely assumed in stochastic groundwater models, the one‐particle…
Influence of deterministic trend on the estimated parameters of GARCH(1,1) model
AbstractThe log returns of financial time series are usually modeled by means of the stationary GARCH(1,1) stochastic process or its…
Serial correlation of detrended time series
AbstractA preliminary essential procedure in time series analysis is the separation of the deterministic component from the random one. If…
