- Opis:
- As natural relaxations of pancyclic graphs, we say a graph $G$ is $k$-pancyclic if $G$ contains cycles of each length from $k$ to $|V(G)|$ and $G$ is weakly pancyclic if it contains cycles of all lengths from the girth to the circumference of $G$, while $G$ is weakly $k$-pancyclic if it contains cycles of all lengths from $k$ to the circumference of $G$. A cycle $C$ is chorded if there is an edge between two vertices of the cycle that is not an edge of the cycle. Combining these ideas, a graph is chorded pancyclic if it contains chorded cycles of each length from $4$ to the circumference of the graph, while $G$ is chorded $k$-pancyclic if there is a chorded cycle of each length from $k$ to $|V(G)|$. Further, $G$ is chorded weakly $k$-pancyclic if there is a chorded cycle of each length from $k$ to the circumference of the graph. We consider conditions for graphs to be chorded weakly $k$-pancyclic and chorded $k$-pancyclic.
