Let us post first the lecture of Andrei Desnitsky at St. Vladimir's. Professor Desnitsky visited St. Vladimir's on March 20, 2014. The lecture is not short, but it is very interesting well worth listening to. This was recorded with older digital recording equipment and thus the quality is not perfect. But it is not terrible either. :) We have better equipment now, and we plan to begin using this equipment in the near future. So very soon the quality of the recordings should improve.
