One World Optimization Seminar

Since the outbreak of the coronavirus pandemic, the entire world has been forced to slow down. The scientific community has been no exception with cancellations of conferences, seminars and research visits. We are all forced to build up new communication channels and the One World Optimization Seminar is an attempt to keep our community together. The short term goal is to provide access to a seminar for as many researchers as possible. For the indefinite future, the seminar is intended to foster ideas among our truly global research community and to help reduce our impact on climate change.

 Organizers

The One World Optimization Seminar is organized by Radu Ioan Boț (University of Vienna), Shoham Sabach (Technion - Israel Institute of Technology Haifa) and Mathias Staudigl (Maastricht University).

 How it works

We use zoom, a simple webinar tool for which only the host (University of Vienna in this case) needs a license and all other participants can log-in via a link that will be sent by e-mail together with the room password to the mailing list the day before each talk. Just click the link and fill in the password and you will be sent to the webinar room. There will be a host with control over the microphones.

Some basic rules for participating at the seminar:

  • Please log-in with your name. 
  • There is a group chat. To ask a question, please indicate you would like to ask and your microphone will be turned on. Alternatively, write a question in the chat.
  • You can chat with every participant in a private chat.

 Mailing List

You are kindly invited to join the mailing list on which the next speaker at the One World Optimization Seminar will be announced, and you will receive the access information (link of the zoom-room and the corresponding password) the day before each talk. Please enter your contact information below.
