On 3-Term Arithmatic Progressions - Why is it so difficult?
Endre Szemeredi
Rutgers University
We are going to discuss an innocent looking combinatorial problem. Is
it true that a dense set of integers always contains a 3-term
arithmatic progression. We compare the strengths of the elementary and
analytic techniques.
**Please note that there will be a wine and cheese reception after the
colloquium to celebrate Prof Szemeredi's recent Steele Prize
