Upper bounds for double exponential sums along a subsequence
Christopher J. White
We consider a class of double exponential sums studied in a paper of Sinai and Ulcigrai. They proved a linear bound for these sums along the sequence of denominators in the continu…

Group automorphisms with prescribed growth of periodic points, and small primes in arithmetic progressions in intervals
Alan Haynes, Christopher White
We investigate the question of which growth rates are possible for the number of periodic points of a compact group automorphism. Our arguments involve a modification of Linnik's T…
