### Jinha Kim (김진하), Collapsibility of Non-Cover Complexes of Graphs

Room B232 IBS (기초과학연구원)Let $G$ be a graph on the vertex set $V$. A vertex subset $W \subset V$ is a cover of $G$ if $V \setminus W$ is an independent set of $G$, and $W$ is a non-cover of $G$ if $W$ is not a cover of $G$. The non-cover complex of $G$ is a simplicial complex …
