On changes of variable that preserve convergence and absolute convergence of Fourier-Haar series
K. R. Bitsadze Ivane Javakhishvili Tbilisi State University, Tbilisi, Georgia
Abstract:
It is established that among all the differentiable homeomorphic changes of variable only the functions $\varphi_1(x)=x$ and $\varphi_2(x)=1-x$ for $x\in[0,1]$ preserve convergence everywhere of the Fourier-Haar series. The same is true for absolute convergence everywhere.
Bibliography: 8 titles.
Keywords:
Fourier-Haar series, changes of variable.
