Program
The time of the talks have been carefully chosen in order to be as suitable as possible for all the Invited Speakers, taking into account the fact that scientists from at least three different continents will participate in the Workshop.
Most of the talks will last 30’+5’, and few of them 25’+5’. Discussion sessions will last (at least, but most likely more than) 30’. Especially after the 2nd session of each day, discussion sessions can go on for hours without problem.
You can find below the program with all the scheduled talks.
You can now download the abstracts.
Video recordings of the talks and discussion sessions can be found at this YouTube Channel.
