Some of my lectures, in pdf

  • Mostly I do not post my lectures, since regularly they contain much more stuff than what I spoke about in my lecture, they are prepared in two forms: with stops and without stops, and -- what is the most important point -- they still need some (actually, a lot) extra polishing.
  • If I post a lecture, I still may improve it, add explanations to it, later.
