Geometry Search for the term Geometry in any field. Queries are case-independent.
Funct* Wildcard queries are specified by * (e.g. functions, functorial, etc.). Otherwise the search is exact.
"Topological group" Phrases (multi-words) should be set in "straight quotation marks".

Chebyshev | Tschebyscheff The or-operator | allows to search for Chebyshev or Tschebyscheff.

This book presents a connected account of the author’s many works on upper and lower bounds for

T T+H |ζ(σ+it)| 2k dt

and related integrals. Although most of these results have therefore appeared before, it is convenient to have them collected together, with the proofs based on common principles, which are established here in the first two chapters.

The statements of many of the theorems are long and involved. As two pithy examples we mention: (1) Let z be a complex number of modulus 1, and let cloglogTHT with a sufficiently large constant c. Then

max TtT+H |ζ(1 2+it) z |exp3 4 logy loglogy·

(2) If H=T 1 2+ε with ε>0 constant, then

T T+H |ζ(1 2+it)| 2/k dt ε H(logT) 1/k 2

for any positive integer k.
