From the PREFACE. THE book of this tract has been not on time by means of quite a few motives, and i'm now forced to factor it with no Dr Riesz's assist in the ultimate correction of the proofs. This has at any fee, one virtue, that it provides me the possibility of announcing how wide awake i'm that no matter what worth it possesses is due as a rule to his contributions to it, and specifically to the actual fact, that it includes the 1st systematic, account of his appealing conception of the summation of sequence through 'typical means'.

Forbidden Integer Ratios of Consecutive Power Sums 17 Part (g) below arose in collaboration with Jan Büthe and we only provide a sketch of the proof here.

535 Forbidden Integer Ratios of Consecutive Power Sums Ioulia N. Baoulina and Pieter Moree To the memory of Prof. m 1/k denote a power sum. m/ of two consecutive power sums is never an integer. We will develop some techniques that allow one to exclude many integers as a ratio and combine them to exclude the integers 3 Ä Ä 1501 and, assuming a conjecture on irregular primes to be true, a set of density 1 of ratios . To exclude a ratio one has to show that the Erd˝os–Moser type equation . m/ D mk has no non-trivial solutions.
