The retreat at half-time of the SFB-TRR 195 with a view to the future takes place from Monday, 18th February to Thursday, 21st February, in the Ebernburg in Bad Münster am Stein. The organisors are Hannah Markwig, Gunter Malle and Michael Kunte.
The main intention is to strengthen cooperation within SFB-TRR 195. Therefore, there will only be very few plenary lectures, instead all mathematical and all software focuses should be given enough opportunity to retreat and work together. In addition, there will be overview lectures for each mathematical focus and also from the OSCAR project, which generally explain how the status of the respective subprojects and their embedding in the overall objective is.
The second focus of the retreat will be the strategic development of the SFB-TRR 195. The aim of the retreat is the preparation of a first list of preliminary projects of the second funding period.
In addition, the second meeting of the IRTG seminar of the PhD-students in the SFB-TRR 195 will be held during the retreat.

Abstracts of the talks:
Gerhard’s talk: This talk is intended as a survey, addressing non-specialists, on finite simple groups. After introducing some of them, I will focus on the fundamental questions concerning their subgroups and linear representations. Using specific examples, I will comment on the state of art with respect to these questions.
Mohamed’s talk: Chevalley proved that the image of an algebraic morphism between algebraic varieties is a constructible set. Examples are orbits of algebraic group actions. A constructible set in a topological space is a finite union of locally closed sets and a locally closed set is the difference of two closed subsets. Simple examples show that even if the source and target of the morphism are affine varieties the image may neither be affine nor quasi-affine. In this talk I will present an Gröbner-basis-based algorithm which computes the constructible image of a morphism of affine spaces.

Since the presence of all PIs is essential, a room will be reserved for each PI. We ask postdocs, doctoral students and others to register with Michael Kunte or Barbara Ermisch via email until November 30th, 2018.
The Ebernburg in Bad Münster am Stein can be easily reached by train (train station “Bad Münster am Stein”) or car from all main locations.
If the weather is good, we also organize a group trip by bicycle from Kaiserslautern.
