3. Examples (Analysis) of Non-Classical Games in Combinatorial Geometry

Andrejs Cibulis

Discrete Mathematics

Oral presentation

Some games using polyforms (pentominoes, hexiamonds) are considered.

5. APE-Shapes – Polyominoes, Polyiamonds and Polyhexes

Elīna Buliņa

14/02/2024, 14:35

Discrete Mathematics

Oral presentation

The talk will deal with the question of what values the number of edges
can take for APE-polygons on square, triangular and hexagonal grids.

4. Families of Perfect Polyiamonds as Formal Languages

Kalvis Apsītis (University of Latvia)

Discrete Mathematics

Oral presentation

We study n-polyiamonds with the restriction: Their sides lengths are all numbers between 1 and n in this order. Each polyiamond has a unique encoding in a 6-letter alphabet. We study formal grammars to describe interesting families of such polyiamonds.

1. A generalization of differences and connections to weak BCK-algebras

Insa Kremere

Discrete Mathematics

Oral presentation

We investigate conditions under which a poset equipped with a weak difference gives rise to a weak BCK-algebra whose subtraction operation coincides with the weak difference for comparable elements.
