| Session | Organisers | Semi-Plenary speaker |
| Functional Analysis in Topology | Damian Sobota | Grzegorz Plebanek (Wroclaw) |
| Continuum theory | Ana Anusic, Jan Boronski | Aleksandra Kwiatkowska (Wroclaw) |
| Foliation theory | Olga Lukina, Hiraku Nozawa | Sam Nariman (Purdue University) |
| Geometric group theory | Kasia Jankiewicz, Rachel Skipper, Daniel Studenmund, Yash Lodha | Sebastian Hensel (Ludwich-Maximilian University Munich) |
| Set-theoretic topology | Boaz Tsaban, Lyubomyr Zdomsky | Leandro Aurichi (Sao Paulo) |
| Tiling space | Henna Koivusalo, Jamie Walton | Lorenzo Sadun (Austin) |
| Topological dynamics | Lori Alvin, Lubomir Snoha, | Xiangdong Ye (Hefei) |
Six of the special sessions are connected in pairs:
Continuum Theory ⇔ Topological Dynamics
Tiling Spaces ⇔ Foliation Theory
Set-Theoretic Topology ⇔ Functional Analysis
These pairs have in principle no parallel lectures,
so people in one session can visit the lectures of the paired session.
