Slides I try to prepare a LaTex beamer presentation for all talks. If I gave a LaTex beamer-talk, then I will upload the corresponding slides here. Talks without a LaTex beamer presentation are not mentioned. Note that these are delivered “as they are”, with no attempt at improving them.

My paper got accepted. The arXiv version of this paper was updated. My paper got accepted. The arXiv version of this paper was updated. "There are two ways to do mathematics. The first is to be smarter than everybody else. The second way is to be stupider than everybody else - but persistent." - based on a quotation from Raoul Bott.
