DESCRIPTION:Seminar Québec-Vermont Number Theory\n\nTitle: Breaking the log
 arithmic barrier in Roth's theorem\n\nAbstract:We present an improvement t
 o Roth's theorem on arithmetic progressions\, implying the first non-trivi
 al case of a conjecture of Erdős: if a subset A of {1\,2\,3\,...} is not t
 oo sparse\, in that the sum of its reciprocals diverges\, then A must cont
 ain infinitely many three-term arithmetic progressions. Although a problem
  in number theory and combinatorics on the surface\, it turns out to have 
 fascinating links with geometry\, harmonic analysis and probability\, and 
 we shall aim to give something of a flavour of this.\n\nWeb site : http://

 ion\, veuillez communiquer à/For details\, please contact: martinez [at] c
