Наредни састанак Семинара биће одржан у петак, 27. септембра 2024. године у сали 301ф Математичког института САНУ. У питању је заједнички састанак са Логичким семинаром. Биће одржана два предавања.
Прво предавање: 27. септембар са почетком у 14.15.
Предавач: Zoltan Vidnyánszky, Eotvos Lorand University
Наслов предавања: DESCRIPTIVE AND DISTRIBUTED
Апстракт: In my talk I will discuss a recently uncovered connection between two, seemingly unrelated fields: descriptive combinatorics and distributed computing. Descriptive combinatorics investigates the behavior of graphs on the real numbers, restricting the focus to ones which are somewhat nice (e.g., Borel). Distributed computing is a branch of computer science concerned with solving graph theoretic problems on large (but finite) networks. It turns out that very often people in the two fields worked on exactly the same problems and used exactly the same ideas. I will discuss this connection and some instances of transferring techniques back-and-forth between the two fields.

Друго предавање: 27. септембар са почетком у 15.30.
Предавач: Ying Zhang, University of Toronto
Наслов предавања: COHERENT SEQUENCES IN HIGHER DIMENSION
Апстракт: I will discuss higher dimensional coherences sequences, generalizing the 1-dimensional ones studied extensively by Todorcevic, whose formulation is connected to certain problems in homological algebra. I will introduce the corresponding notions of coherence and triviality. Then I will focus on some recent non-vanishing results at the level of the second uncountable cardinal and dimension 2. This is joint work with Jeffrey Bergfalk and Chris Lambie-Hanson.
