From uniform to statistical convergence of binomial-type operators

6 years ago

AbstractSequences of binomial operators introduced by using umbral calculus are investigated from the point of view of statistical convergence. This…

AbstractIn this paper we solve by method of lines (MoL) a class of pseudo-parabolic PDEs defined on the real line.…

Modifying an approximation process using non-Newtonian calculus

AbstractIn the present note we modify a linear positive Markov process of discrete type by using so called multiplicative calculus.…

Linear positive operators constructed by using Beta-type bases

On the convergence of the Newton-GMBACK method

6 years ago

AbstractWhen the GMBACK solver is used in the Newton iterates, the iterates may be written either as inexact Newton iterates…

Ergodic simulations of diffusion in random velocity fields
