Analysis of aggregation-based multigrid
AbstractAggregation-based multigrid with standard piecewise constant like prolongation is investigated. Unknowns are aggregated either by pairs or by quadruplets; in…
Unsteady boundary layer flow and heat transfer over a stretching sheet
AbstractUnsteady two-dimensional boundary layer flow and heat transfer over a stretching flat plate in a viscous and incompressible fluid of…
Mixed convection flow near an axisymmetric stagnation point on a vertical cylinder
AbstractThe mixed convection flow near an axisymmetric stagnation point on a vertical cylinder is considered. The equations for the fluid…
On the nonmonotone behavior of the Newton‐GMBACK method
AbstractGMBACK is a Krylov solver for large linear systems, which is based on backward error minimization properties. The minimum backward…
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…
