    Induced hereditary graph classes and clousure operation

  • Original language description

    In this paper we show that if $G$ is a 2-connected $CP_{7}$-free graph, then $mbox{cl}(G)$ is $CN_{112}$-free or $mbox {cl}(G)$ belong to some 4 fully described infinite classes of exceptions. We also show that there is a similar relation for 2-connected $CN_{112}$-free and $CN$-free graphs (with $ {cal C}^{N}_{1},{cal C}^{N}_{2},{cal C}^{N}_{3},{cal C}^{N}_{4},{cal C}^{N}_{3a}$ and ${cal C}^{N}_{4a}$ at exceptions). From these propositions it follows that if $G$ is 3-connected $CP_{7}$-free graph, then $mbox{cl}(G)$ is $CN$-free.

    Stabilita dědičných třid grafů při uzávěrové operaci

  • Czech description

    V tomto článku ukážeme, že když $G$ je 2-souvislý $CP_{7}$-free graf, pak $mbox {cl}(G)$ je $CN_{112}$-free nebo $mbox {cl}(G)$ patří do některé z 4 nekonečných tříd grafů. Rovněž ukážeme že existuje vztah mezi 2-souvislými $CN_{112}$-free a $CN$-freegrafy (až na výjimky $ {cal C}^{N}_{1},{cal C}^{N}_{2},{cal C}^{N}_{3},{cal C}^{N}_{4},{cal C}^{N}_{3a}$ a ${cal C}^{N}_{4a}$). Z těchto výsledků vyplývá, že pokud $G$ je 3-souvislý $CP_{7}$-free graf, pak $mbox{cl}(G)$ je $CN$-free.
