David Schrittesser
I am currently a postdoc in the
noncommutative geometry group
at the Department of Mathematical Sciences, University of Copenhagen, where I work with
Asger Törnquist.
Research Profile
My research is in
set theory; my primary interests are
forcing and descriptive set theory.
My Erdös number is 11 (using binary notation).

Slides

If you are not a set theorist, maybe you will enjoy these slides;
I made them with a general mathematical audience in mind, for a talk
in the descriptive set theory seminar in Copenhagen on January 9th 2014.

Here are some slides for my talk at the 4th European Set Theory Conference in Barcelona, in July 2013.
