A study of 𝛼-variation. I
F. W. Gehring · Transactions of the American Mathematical Society · 1954
This paper is based on the notion of the higher variation of a function introduced by N. Wiener [9] while studying the Fourier coefficients of a function with bounded variation.L. C. Young applied this idea to derive a new existence theorem for Stielt] es integration and later collaborated with E. R. Love in publishing a number of papers on subjects related to this concept.
