The goal of this endeavor is to run a seminar on the platform Zoom on a weekly basis, perhaps with alternating time slots each of which covers at least three out of four of Europe, North America, Asia, and New Zealand/Australia.
This initiative is born out of the wish to organize something positive in the current situation where normal seminars, conferences and meeting activities are put on hold. If everything runs well, we might even like to continue this seminar series in the future.
