Almost-orthogonality of restricted Haar functions [PDF]
We consider the Haar functions h I h_I on dyadic intervals. We show that if p > 2 3 p>\frac 23 and E ⊂ [ 0 , 1 ] E\subset [0,1] , then the set of all functions ‖

Coefficients of multiple Fourier-Haar series and variational modulus of continuity
In this paper, we introduce the concept of a variational modulus of continuity for functions of several variables, give an estimate for the sum of the coefficients of a multiple Fourier-Haar series in terms of the variational modulus of continuity, and ...

Wavelet p-analogs of the discrete Haar transform [PDF]
Two $p$-analogs (for $p>2$) of the discrete version of the Haar system in vector symbolism are proposed and fast algorithms are constructed based on them.

Coarse-graining and the Haar wavelet transform for multiscale analysis
Background Multiscale entropy (MSE) has become increasingly common as a quantitative tool for analysis of physiological signals. The MSE computation involves first decomposing a signal into multiple sub-signal ‘scales’ using a coarse-graining algorithm ...

Haar Wavelet Method for Solving High-Order Differential Equations with Multi-Point Boundary Conditions [PDF]
In This paper, the developed Haar wavelet method for solving boundary value problems is described. As known, the orthogonal Haar basis functions are applied widely for solving initial value problems, but In this study, the method for solving systems of ...

Bruckner--Garg-type results with respect to Haar null sets in $C[0,1]$ [PDF]
A set $\mathcal{A}\subset C[0,1]$ is \emph{shy} or \emph{Haar null } (in the sense of Christensen) if there exists a Borel set $\mathcal{B}\subset C[0,1]$ and a Borel probability measure $\mu$ on $C[0,1]$ such that $\mathcal{A}\subset \mathcal{B}$ and ...
