SUMMARY:Semi-algebraic Combinatorics
DESCRIPTION:Speaker: Janos Pach (EPFL\, Lausanne and\nRenyi Institute\, Bud
 apest)\n\nAbstract: \nAbstract: By Ramsey's theorem\, any system of n segm
 ents in the plane has roughly log $n$ members that are either pairwise dis
 joint or pairwise intersecting. Analogously\, any set of n points $p(1)\,\
 \cdots p(n)$ in the plane has a subset of roughly loglog $n$ elements with
  the property that the orientation of $p(i)p(j)p(k)$ is the same for all t
 riples from this subset with $i\n
