Center node: "a polynomial kernel for 3 leaf power deletion"
  Abstract: A graph $G$ is an $\ell$-leaf power of a tree $T$ if $V(G)$ is equal to the set of leaves of $T$, and distinct vertices $v$ and $w$ of $G$ are adjacent if and only if the distance between $v$ and $w$ in $T$ is at most $\ell$. Given a graph $G$, the $3$-leaf Power Deletion problem asks whether there is a set $S\subseteq V(G)$ of size at most $k$ such that $G\setminus S$ is a $3$-leaf power of some tree $T$. We provide a polynomial kernel for this problem. More specifically, we present a polynomial-time algorithm for an input instance $(G,k)$ to output an equivalent instance $(G',k')$ such that $k'\le k$ and $G'$ has at most $O(k^{14}\log^{12}k)$ vertices.
