Applying Haar-Sinc Spectral Method for Solving time-fractional Burger Equation [PDF]

open access: yesMathematics and Computational Sciences
Haar-Sinc spectral method is used for the numerical approximation of time fractional Burgers’equations with variable and constant coefficients. The main idea in this method is using a linear discretization of time and space by combination of Haar and ...

The Haar System in the Preduals of Hyperfinite Factors [PDF]

open access: yesCanadian Mathematical Bulletin, 2011
AbstractWe shall present examples of Schauder bases in the preduals to the hyperfinite factors of types II1, II∞, IIIλ, 0 ≤ 1. In the semifinite (respectively, purely infinite) setting, these systems form Schauder bases in any associated separable symmetric space of measurable operators (respectively, in any non-commutative Lp-space).

On Haar Systems for Groupoids

open access: yesZeitschrift für Analysis und ihre Anwendungen, 2018
It is shown that a locally compact groupoid with open range map does not always admit a Haar system. It then is shown how to construct a Haar system if the stability groupoid and the quotient by the stability groupoid both admit one.

Simulation of a non‐linear, time‐variant circuit using the Haar wavelet transform

open access: yesIET Science, Measurement & Technology, 2022
Wavelet theory has disentangled numerous complexities, including those pertinent to transient and steady‐state responses of systems, when Laplace and Fourier transforms face insoluble obstacles. Reactive linear components (e.g.
