The equivalence between the T-stabilities of Mann and Ishikawa iterations

Abstract We show that T-stability of Mann and Ishikawa iterations are equivalent. AuthorsB.E. Rhoades S.M. Soltuz (Tiberiu Popoviciu Institute of…

Evaluation of overshooting errors in particle methods for diffusion by biased global random walk

AbstractThe adjustment of grid steps which guarantees that particles methods yield no numerical diffusion inevitably induces overshooting errors in the…

On the accuracy of Stoermer/Verlet method as the numerical integrator of the n-body problem – Application to solar system

AbstractThe Newton-Störmer/Verlet-leapfrog method (S/V) is a symplectic and symmetric one of order two, which, when applied to separable Hamiltonian dynamical systems,…

Numerical investigations on ergodicity of solute transport in heterogeneous aquifers

AbstractDarcy velocities for lognormal hydraulic conductivity with small variance and finite correlation length were approximated by periodic random fields. Accurate…

Evaluation of the first‐order approximations for transport in heterogeneous media

AbstractLongitudinal dispersion coefficients in given realizations of the transport computed by two currently used approximations of the first‐order in velocity…

On a compound approximation operator of D.D. Stancu type

AbstractIn this note we consider a linear and positive compound approximation operator of D.D. Stancu type depending of several parameters.…

Rate of approximation for certain Durrmeyer operators

AbstractIn the present note, we study a certain Durrmeyer type integral modification of Bernstein polynomials. We investigate simultaneous approximation and…

Bilateral approximations of solutions of equations by order three Steffensen-type methods

Abstract We study the convergence of a method of Steffensen-type, which is obtained from the Lagrange polynomial of inverse interpolation with…
