Some arithmetic means connected with Fourier series
BOSANQUET 1. Introduction.It is known that if a series^0» is bounded (C, y), y à -1, then it is either summable (C, y + b), for every 5>0, or not summable 04).fFurther a necessary and sufficient condition for it to be bounded (C, 7) is that it should be bounded …
