The event (Learning Week 1 and 2nd workshop) was first planned on 23 March - 03 April 2020. However, due to Covid19 pandemic, it was cancelled with notifications sent to participants on 09 March 2020.

The new date of this event was then decided from 03 to 11 September 2020 in which:

  • POEMA first learning week in Konstanz: September 03 - 08, 2020 (Thursday to Tuesday)
  • POEMA 2nd workshop in Konstanz: September 09 - 11, 2020 (Wednesday to Friday)

However, according to the uncertainty of travel restriction due to the pandemic, POEMA consortium has just decided to organize the learning weeks online from the end of May to September 2020. Regarding the workshop, depending on the situation in Europe in the coming months, we will decide if it can be organized in September or later this year. We will inform you as soon as possible.

The 2nd workshop in Konstanz is dedicated to the foundations of polynomial optimization. There will be talks in a broad range of topics by established expert researchers. In addition, the doctoral students in the POEMA network will have the opportunity to present and discuss their first research results.

Other students outside POEMA network who are interested in the topic are welcome to participate.


The 2nd workshop will be organized at:

Fachbereich Mathematik und Statistik
Universität Konstanz
78457 Konstanz


The event is free. However, the number of places is limited and registration is strictly necessary.

We will open the registration process as soon as the event is confirmed.
