QUANTITIVE VERSIONS OF ROTH'S THEOREM ON ARITHMETIC PROGRESSIONS
Summary:
In this thesis we study quantitative versions of Roth's theorem
on arithmetic progressions of length 3. We denote by R(N) the cardinality
of the largest subset of {1,...,N} which does not contain non-trivial
arithmetic progressions of three terms. Roth proved in 1953 that R(N)<<
N/loglog N and later better upper bounds were given by Szemeredi, Bourgain
and Sanders. We present Roth's original argument and more recent works of
Croot, Bloom and Sisask. The last one is a work of Bloom and Sisask who
managed to prove the upper bound R(N) << N/(log N)^c for some c>1.
