DESCRIPTION:Speaker: Jacob Fox (Stanford)\n\nTitle: Three-color van der Wae
 rden numbers grow super-exponentially \n\nAbstract: The van der Waerden nu
 mber w(k\;r) is the minimum positive integer N such that every r-coloring 
 of the positive integers up to N contains a monochromatic k-term arithmeti
 c progression. Estimating these numbers has remained a challenging open pr
 oblem for the past century. In this talk\, we will sketch a proof that the
  three-color van der Waerden number w(k\;3) grows faster than any exponent
 ial in k. This settles several longstanding conjectures in the area. Time 
 permitting\, we will discuss a variety of related results. Based on joint 
 work with Zach Hunter.
