Description
Stratified spaces occur naturally in high- and low-dimensional topology, various fields of pure mathematics, including algebraic geometry and number theory, and also in more applied fields, such as the study of configuration spaces for robot motion planning. In recent years, there has been extensive interest and success in expanding to stratified spaces the triumphs of algebraic topology in manifold theory, including the vast progress in the mid-20th century on signatures, characteristic classes, surgery theories, and the special homological properties of nonsingular analytic and algebraic varieties, such as the Kähler package. Yet such extensions from manifold theory to stratified space theory are rarely straightforward; they tend to involve the discovery and study of subtle interactions between local and global behavior. Furthermore, research in these areas turns out to have a rich interaction with the question being addressed by the Analysis of Singular Spaces program running simultaneously at MSRI of how to do analysis on spaces that are not locally Euclidean. The workshop will be organized into days dedicated to each of the four main themes: topology of complex varieties, signature theory on singular spaces, L^2 and intersection cohomology, and mixed Hodge theory and singularities. Each day except Wednesday will include one introductory talk aimed at audience members from both topology and analysis of singular spaces, and three research talks. There will also be room for some shorter talks by PhD students or recent graduates and for a few talks on Wednesday morning on related subjects that do not fit one of these categories. A block of rooms has been reserved at the Rose Garden Inn. Reservations may be made by calling 1-800-992-9005 OR directly on their website.

Students, recent Ph.D.'s, women, and members of underrepresented minorities are particularly encouraged to apply. Funding awards are typically made 6 weeks before the workshop begins. Requests received after the funding deadline are considered only if additional funds become available.

Show Lodging

MSRI does not hire an outside company to make hotel reservations for our workshop participants, or share the names and email addresses of our participants with an outside party. If you are contacted by a business that claims to represent MSRI and offers to book a hotel room for you, it is likely a scam. Please do not accept their services.

MSRI has preferred rates at the Hotel Shattuck Plaza, depending on room availability. Guests can call the hotel's main line at 510-845-7300 and ask for the MSRI- Mathematical Science Research Institute discount. To book online visit this page (the MSRI rate will automatically be applied).

MSRI has preferred rates at the Graduate Berkeley, depending on room availability. Reservations may be made by calling 510-845-8981. When making reservations, guests must request the MSRI preferred rate. Enter in the Promo Code MSRI123 (this code is not case sensitive).

MSRI has preferred rates at the Berkeley Lab Guest House, depending on room availability. Reservations may be made by calling 510-495-8000 or directly on their website. Select "Affiliated with the Space Sciences Lab, Lawrence Hall of Science or MSRI." When prompted for your UC Contact/Host, please list Chris Marshall (coord@msri.org).

MSRI has a preferred rates at Easton Hall and Gibbs Hall, depending on room availability. Guests can call the Reservations line at 510-204-0732 and ask for the MSRI- Mathematical Science Research Inst. rate.
