Deformation Theory

 

University of Colorado at Boulder

Seminar on 

Deformation Theory

   Spring 2012

Tuesdays 3 - 4 PM in MATH 350

This is a working seminar meant to introduce deformation theory.  The seminar will be held in MATH 350.  The mathematics department is at the corner of Colorado Ave and Folsom St.  For a map of the campus, click here.  This is a continuation of last semester's Seminar on Deformation Theory (although prerequisite material from that semester will be reviewed as needed).

Schedule of upcoming talks:

January 31
 Markus Pflaum
 Introduction to deformation quantization
February 7
 David Wayne
 How to generalize the notion of a sheaf
February 14
 David Wayne
 Examples and applications of Grothendieck sites
February 21 FRAGMENT seminar
 FRAGMENT seminar
February 28 Markus Pflaum
