Dear friends of hikes and mathematics,

you are cordially invited to a hike that will take place on Saturday, October 18, 2025.

We will go to Nihov by the train that leaves from Kralovo Pole at 8:07 and from the main station at 7:53. You would need a ticket for 5 zones outside Brno.

The planned route of length 21 km, with elevation +600 -800 m, mostly avoids marked trails and will lead us to Tisnov (with frequent connections to Brno). There are several places to leave the route, with connections to Brno every two hours.

We look forward to seeing you!

Pavel Francírek and Michal Kunc, organizers

Dear friends of mathematics,

mathematical hike 49, to which we cordially invite you, will take place on Saturday May 24th 2025. Meet at 9:30 at the tram 1 terminus in Řečkovice.

The route is 20 km along hiking paths and also following some roadways, with the finish back in Řečkovice.

More precisely:
- From Řečkovice to Mokrá Hora, then along the red trail through Lelekovice to the Babí lom lookout tower and to Kuřim.
- From Kuřim to the Baba Nature Park, through it to Řečkovice.
You can end your participation also after 13 km in Kuřim, from where it is possible to return to Brno by train or bus.

Looking forward to see you,

Pavel Francírek and Jonatan Kolegar, organizers

Model Theory, Exponentiation and Quasiminimality

Mon 31.3. 14:00-15:00 (seminar room, 2nd floor)
Tue 1.4. 11:00-12:00 (M4)
Wed 2.4. 14:00-15:00 (M5)
Thu 3.4. 10:00-11:00 (seminar room, 2nd floor)

Abstract: Model Theory is a way of looking at mathematical concepts which is sensitive to the choice of language we use to describe them. One of its achievements is to classify different mathematical theories according to their complexity. In this series of talks I will survey some of the work done towards understanding the model theory of exponential fields, including the real exponential and Zilber’s approach to the complex exponential field. We know from Wilkie that the real exponential field is not too complicated (it is o-minimal) and this has good consequences in geometry, in number theory, and even in machine learning. For the complex exponential, we do not know if it is tame (quasiminimal) or whether it is maximally complicated (interpreting both reals and integers). I will explain progress towards proving that it is tame.
