DESCRIPTION:The density Hales-Jewett theorem has the same\nrel
ationship to the Hales-Jewett theorem that SzemerĂ©
di's\ntheorem has to van der Waerden's theorem. Un
til recently\,\nthe only known proof was long and
complicated and relied\nheavily on ergodic theory.
Recently an elementary and much\nsimpler proof ha
s been discovered. Unusually\, the research\nwas c
arried out in the open by several people on blogs
and \na wiki. This talk will\, however\, be about
the mathematics\nrather than the unusual process t
hat led to it.
