Constructive twin-width for posets of small width

Constructive twin-width for posets of small width
Abstract:
Twin-width je invariant definován primárně pro grafy, ale rozšířen i na další struktury. Bylo ukázáno, že třídy s malou twin-width mají pěkné vlastnosti, např. se na nich dají efektivně vyhodnocovat prvořádové formule (tzv. FO model checking). Tato práce zkoumá twin-width posetů omezené šířky (což je maximální velikost antiřetězce). Nejprve ukazujeme, že posety šířky 2 mají twin-width nejvýše 2 a že …more
Abstract:
Twin-width is an invariant defined primarily for graphs but extended to other structures as well. It has been shown that classes of small twin-width have some nice properties, such as efficient FO model checking. In this thesis, we study the twin-width of posets with bounded width (which is the maximum size of an antichain). First, we show that posets of width 2 have twin-width at most 2 and that this …more
