(LaTeX) Abstract:
In the Connected Dominating Set problem we are given as input a graph $G$ and a
positive integer $k$, and are asked if there is a set $S$ of at
most $k$ vertices of $G$ such that $S$ is a dominating set of
$G$ and the subgraph induced by $S$ is connected. This is a
basic connectivity problem that is known to be NP-complete, and it
has been extensively studied using several algorithmic
approaches. In this paper we study the effect of excluding short
cycles, as a subgraph, on the {\em kernelization complexity} of
Connected Dominating Set.
Kernelization algorithms are polynomial-time algorithms that
take an input and a positive integer $k$ (the {\em parameter})
and output an equivalent instance where the size of the new
instance and the new parameter are both bounded by some function
$g(k)$. The new instance is called a $g(k)$ {\em kernel} for
the problem. If $g(k)$ is a polynomial in $k$ then we say that
the problem admits polynomial kernels. The girth of a graph $G$
is the length of a shortest cycle in $G$. It turns out that
Connected Dominating Set is ``hard'' on graphs with small cycles, and becomes
progressively easier as the girth increases. More specifically,
we obtain the following interesting trichotomy: Connected Dominating Set
\begin{itemize}
\item does not have a kernel of {\em any} size on graphs of girth
$3$ or $4$ (since the problem is W[2]-hard);
\item admits a $g(k)$ kernel, where $g(k)$ is $k^{O(k)}$, on
graphs of girth $5$ or $6$ but has {\em no} polynomial kernel
(unless the Polynomial Hierarchy (PH) collapses to the third
level) on these graphs;
\item has a cubic ($O(k^3)$) kernel on graphs of girth at least $7$.
\end{itemize}
While there is a large and growing collection of parameterized
complexity results available for problems on graph classes
characterized by excluded {\em minors}, our results add to the
very few known in the field for graph classes characterized by
excluded {\em subgraphs}.
