KK-Theory of Operator Algebras and Noncommutative Geometry

May 5 to May 14, 2008

The Sixth 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 noncommutative geometry, operator algebras and related topics 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 annual spring institute on NCGOA will be followed by a workshop on Noncommutative geometry and geometry over the field with one element from May 15 to May 18, 2008. Click here for more information.

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

    Reimbursement policy.

    Please see Traveling to the United States (The National Academies), US State Department and US State Department Visa Waiver Program for information about visas.

    Please be advised that according to U.S. immigration laws, individuals who enter the U.S. and wish to be reimbursed for travel related expenses should enter only on a B-1, WB or J-1 visa (WT and B-2 visa do not permit reimbursement of any expenses). See the web pages above for visitors entering from Canada and Mexico. Entering on a Visa Waiver is discouraged due to concerns as to how the new law will be interpreted. Please call your local US consulate or embassy and inquire what the rules are pertaining to your country.

    NSF funds can be used for reimbursement of air fare only if a U.S. flag carrier (i.e. a U.S. airline) has been used.

    Upon arriving, please see the staff person at the registration desk for the necessary forms to be filled out and returned prior to your departure. We will need all original receipts for any expenses for which reimbursement is claimed and copies of your visa if applicable. Please note that Vanderbilt may be required to withold US income tax on your reimbursement. Please see Vanderbilt International Tax office for more information.
