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: https://www.youtube.com/c/VisualMath. Talk list: available here.
