Algebraic Geometry Seminar, Fall 2007

Algebraic Geometry Seminar

4:00 - 6:00 p.m.
3088 East Hall

The seminar normally meets from 4:10 to about 6:00 pm, with a break around 5 pm. We encourage speakers to make the first hour of each talk expository and introductory in nature, so that this part of the seminar will be accessible to graduate students and postdocs in other fields. Details and technicalities are welcome (but not required!) after the break.

For more information, contact Rob Lazarsfeld ( rlaz@umich.edu ) .
