## * Conference Papers *

Conference papers are usually numerous and allow one to
significantly extend his/her list of publications.
At the same time conference
papers typically appear, at a later stage, as journal papers.
Hence, I do not see any reason to present
my conference papers here.

For my recent talks see "Resent Talks" item.
