Naredni sastanak Seminara biće održan onlajn u petak, 25. marta 2022. sa početkom u 16 časova preko Zoom platforme.

Predavač: Đorđe Baralić, Matematički institut SANU

Naslov predavanja: SIMPLICIAL COMPLEXES OF POLYOMINO TILINGS

Apstrakt:
A polyomino is a collection of squares of equal size arranged with coincident sides. Firstly introduced by Martin Gardner in 50's they quickly attracted wide interest beside recreational mathematics. We assign a simplicial complex to the problem of regular tiling of a finite region in a square by poliominoes from a given finite set of shapes. It turns out that both combinatorics and topology of these complexes are interesting. Particularly we showed that in some cases they have homotopy type of the wedge of spheres. F vectors of the complexes reveal us some information on partial tilings

Napomena: Predavanje (zoom) je u okviru seminara kojim rukovodi Ivan Limončenko (Moskva, Higher School of Economic). Podsećamo da smo nedavno oglasili predavanje I. Limončenka u okviru zajedničkog topološkog seminara.
