On a connection of number theory with graph theory
Result description
We assign to each positive integer n a digraph whose set of vertices is H={0,1,...,n-1} and for which there is a directed edge from a..H to b.. H if a..b(mod n). We establish necessary and sufficient conditions for the existence of isolated fixed points.We also examine when the digraph is semiregular. Moreover, we present simple conditions for the number of components.

O souvislosti teorie čísel s teorií grafů
Czech description
Každému přirozenému číslu n přiřadíme orientovaný graf s množinou vrcholů H={0,1,...,n-1} tak,že orientovaná hrana jde z a..H do b..H, když a .IDENT.b ( modu ). Stanovíme nutné a postačující podmínky pro existenci izolovaných pevných bodů. Také vyšetřujeme, kdy je orientovaný graf semiregulární. Navíc předkládáme jednoduché vztahy pro počet komponent a délky cyklů.
