On the approximation of the global extremum of a semi-Lipschitz function

4 years ago

AbstractIn this paper one obtains a sequential procedure for determining the global extremum of a semi-Lipschitz real-valued function defined on…

On the Extensions Preserving the Shape of a Semi-Hölder Function

4 years ago

AbstractWe present some results concerning the extension of a semi-Hölder real-valued function defined on a subset of a quasi-metric space,…

Block incremental unknowns for anisotropic elliptic equations

4 years ago

AbstractIn this article, we define the notion of block incremental unknowns for anisotropic elliptic equations. Written in a block structure,…

Analysis of aggregation-based multigrid

4 years ago

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

4 years ago

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

4 years ago

AbstractThe mixed convection flow near an axisymmetric stagnation point on a vertical cylinder is considered. The equations for the fluid…

An implicit numerical spline method for systems for ODEs

4 years ago

Abstract An implicit numerical method is introduced that gives piecewise polynomial spline approximations for the solution of an initial value…

On the nonmonotone behavior of the Newton‐GMBACK method

4 years ago

AbstractGMBACK is a Krylov solver for large linear systems, which is based on backward error minimization properties. The minimum backward…

A mixed iteration for nonnegative matrix factorizations

4 years ago

Abstract We show that, under appropriate conditions, one can create a hybrid between two given iterations which can perform better…

Solving inverse problems via hemicontractive maps

4 years ago

AbstractWe prove a “collage” theorem for hemicontractive maps and we use it for inverse problems. A numerical example is given.…
