1-5 P.M.: 3 talks, speakers:
Dror Bar-Natan (Hebrew University, Jerusalem)
Title: From Stonehenge to Drinfel'd skipping
all the details
Abstract: See here.
Hyam Rubinstein (University of Melbourne):
Title: Minimal surfaces in hyperbolic 3-manifolds
Abstract: It is shown that any hyperbolic
3-manifold of finite
volume admits infinitely many distinct immersed closed
minimal surfaces. Minimal surface theory can be used to
give useful lower bounds on the Heegaard genus of
hyperbolic 3-manifolds and information on how Heegaard
genus grows with taking covering spaces (work with
Aitchison and Schultens).
Peter Teichner (UCSD)
Title: Pulling apart 2-spheres in 4-space
Abstract: We show that any number of disjointly
2-spheres in 4-space can be pulled apart by a link homotopy,
i.e. by a motion in which the 2-spheres stay disjoint but are
allowed to self-intersect. In particular, there is NO
4-dimensional Hopf link.
5:30 P.M.: Party at LIN's

here is 0.7 mile. Turn right into Canyon Crest Town Center, then turn left
after the entrace and Crest Cafe is on your right side.
>From Los Angeles: Take 60 eastbound. Exit at Martin Luther King Boulevard
meet Canyon Crest Drive almost immediately. Turn left onto Canyon Crest,
drive 0.8 mile and you will see the sign of Canyon Crest Town Center. Turn
right into Canyon Crest Town Center, then turn left after the entrace and
