May 9 to May 20, 2005

The Third Annual Spring Institute on Noncommutative Geometry and Operator Algebras is a combination of spring school and international conference. During the school part of the meeting several mini-courses on a variety of topics from NCGOA will be given by leading experts. The conference will comprise a number of invited research talks and short contributions. We strongly encourage students and postdocs to attend this conference. Please read the section on financial aid below regarding information on how to apply for financial support.

The home page of the research group in noncommutative geometry and operator algebras at Vanderbilt University can be found here.


Talks will start at 9:15 am on Monday, May 9, 2005, and end at noon on Friday, May 20, 2005. Friday, May 13, 2005, will be a day off since commencement/graduation will take place at Vanderbilt on that day. All lectures will be held in Lecture Hall 4309, Stevenson Center (for short SC). The seminar room SC 5208 (right next to SC 4309) and the seminar rooms in the math building (e.g. SC 1312, SC 1320, SC 1403, SC 1404) are available for discussions. Limited computer access is available in the computer lab of the mathematics department (SC 1427). Moreover Vanderbilt campus has a wireless network which is accessible from many campus locations.

Directions to the lecture hall. The Stevenson Center consists of several buildings. The mathematics department is located in building 1 and the lecture hall in building 4, which are right next to each other. For more details, please consult the campus map
