On a Theorem of Haar [PDF]

open access: bronzeProceedings of the American Mathematical Society, 1967
Let {4n } be an orthonormal set in L2 [0, 1], n having finite total variation Vn. Haar proved [1] that lim Vtn = co and that consequently On } has an intrinsic ordering according to nondecreasing total variation. He showed, in fact, that in this ordering Vtn > cV/n where c is an absolute constant. A different proof was later given by Rudin [2].

A Haar meager set that is not strongly Haar meager [PDF]

open access: greenIsrael Journal of Mathematics, 2019
Following Darji, we say that a Borel subset $B$ of an abelian Polish group $G$ is Haar meager if there is a compact metric space $K$ and a continuous function $f : K \to G$ such that the preimage of the translate, $f^{-1}(B+g)$ is meager in $K$ for every $g \in G$.

Coefficients of multiple Fourier-Haar series and variational modulus of continuity

open access: yesҚарағанды университетінің хабаршысы. Математика сериясы, 2023
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 ...
