Teaching Fall 2016: Geometry and complexity
Meeting: MWF 10:20 - 11:10 Bloc 624
Fall 2014 I served as Chancellor's Professor at
Institute for the Theory of Computing,
and co-organized (with P. Burgisser, K. Mulmuley and B. Sturmfels) of the semester long program Algorithms and Complexity in Algebraic Geometry During the semester I gave a course on Geometry and Complexity Theory, and have notes for the course.

My travel plans
I am on the editorial board of Foundation of Computational Mathematics, Differential Geometry and its Applications, and Linear Algebra and its Applications.
**DGA special issue on geometry and complexity theory**
The journal Differential Geometry and its Applications http://ees.elsevier.com/dga/ will be having a special thematic issue dedicated to geometry and complexity theory. I encourage you to submit an article for consideration.
I am trying to put together a high quality issue that will increase the visibility of this emerging area. Moreover, having an issue dedicated to the geometry and complexity will increase the visibility of each individual article as well, as previously, articles in the area have been appearing in a wide range of publications. The deadline for submissions is Dec. 31, 2016.
If you submit through the DGA webpage, be sure to include in your cover letter that it is for the thematic issue. If you have any questions about the thematic issue, please do not hesitate to contact me at firstname.lastname@example.org.
