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.
Videos of (some of) my talks can be found here: Click.
