THE theory of functions of a real variable is a subject of fairly recent date and is necessarily expanding as new theorems are discovered and fresh generalisations effected. On the other hand, the ...
It is shown that the Fourier coefficients of functions of $\Lambda$-bounded variation, $\Lambda = \{\lambda_n\}$, are $O(\lambda_n/n)$. This was known for $\lambda_n ...
