Domains via approximation operators [PDF]

open access: yesLogical Methods in Computer Science, 2018
In this paper, we tailor-make new approximation operators inspired by rough set theory and specially suited for domain theory. Our approximation operators offer a fresh perspective to existing concepts and results in domain theory, but also reveal ways ...

The spaces of exponential type vectors of complex degrees of positive operators

open access: yesKarpatsʹkì Matematičnì Publìkacìï, 2013
New classes of interpolation spaces of exponential type vectors of complex degrees of positive operators are defined. Properties of the approximation spaces generated by the considered interpolation spaces are investigated.

Convergence theory for the exact interpolation scheme with approximation vector as the first column of the prolongator and Rayleigh quotient iteration nonlinear smoother [PDF]

open access: yesAPPLICATIONS OF MATHEMATICS, 2017
We extend the analysis of the recently proposed nonlinear EIS scheme applied to the partial eigenvalue problem. We address the case where the Rayleigh quotient iteration is used as the smoother on the fine-level. Unlike in our previous theoretical results, where the smoother given by the linear inverse power method is assumed, we prove nonlinear speed ...

On the steady‐state performance of bias‐compensated LMS algorithm

open access: yesElectronics Letters, 2021
Adaptive filtering algorithms are widespread today owing to their flexibility and simplicity. Due to environments in which they are normally immersed, their robustness against noise has been a topic of interest.
