$(C_n;k)$ - stable graphs with minimum size
Presented by Agnieszka GöRLICH
Type: Oral presentation
Track: General session
Content
A graph $G$ is called $(H;k)$ - {\it vertex stable} if $G$ contains a subgraph isomorphic to $H$ ever after removing any of its $k$ vertices; stab$(H;k)$ denotes the minimum size among the sizes of all $(H;k)$ - vertex stable graphs.
We show that stab $(C_{n};1)$ is one of only two possible values for each $n$ and we give the exact value for infinitely many $n$'s. Furthermore we establish an upper and lower bound for stab $(C_{n};k)$ for $k\geq 2$.
