Geometry Seminar
Courant Institute of Mathematical Sciences, NYU.

Location: room 1314 , Warren Weaver Hall.
Time: Tuesday, 6:00PM to 7:00PM
 (unless mentioned otherwise.)

For more information please contact Prof. Richard Pollack (pollack "AT" cims.nyu.edu).

The geometry seminar covers a wide range of topics in geometry with particular emphasis on discrete geometry, computational geometry and algorithmic real algebraic geometry. Many of the speakers are Courant Institute visitors and postdocs. A seminar talk may cover original research or report on an interesting paper. The seminar is run by Janos Pach, Richard Pollack and Joseph Malkevitch.
