Organizers:   Reinhard Schultz, Xiao-Song Lin and Oliver Dasbach

11:40 :           (informal) lunch at Crest Cafe (directions below)
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 embedded
                       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

Parking: For visitors from other UC's: Please use your parking permit.
         For Non-UC visitors: Please identify yourself as coming for
         the Southern California Topology Colloquium or just math
         conference to get a (free) parking permit.



Directions

Lunch at: Crest Cafe in Canyon Crest Town Center, Tel: 909-784-2233.

Direction:

>From San Diego: Take 215 westbound merging to 60 westbound near Riverside.
Exit at Martin Luther King Boulevard. After crossing the bridge over the
freeway, go straight on to El Cerrito. At the intersection with Canyon
Crest Drive, turn left. Drive on Canyon Crest until you see the sign of
Canyon Crest Town Center. The total drive distance from exiting freeway to
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 and
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
