(LaTeX) Abstract:
We study a general class of problems called $p$-\textsc{$\mathcal{F}$-Deletion}
problems. In an $p$-\textsc{$\mathcal{F}$-Deletion} problem, we
are asked whether a subset of at most $k$ vertices can be deleted from a graph
$G$ such that the resulting graph does not contain as a minor any graph from the
family ${\cal F}$ of forbidden minors. We obtain a number of algorithmic results
on the $p$-\textsc{$\mathcal{F}$-Deletion} problem when $\mathcal{F}$ contains a planar graph. We give
\begin{itemize}

\item a linear vertex kernel on graphs excluding $t$-claw $K_{1,t}$, the star with $t$ leves, as an induced subgraph, where $t$ is a fixed integer.

\item an approximation algorithm achieving an approximation ratio of
$O(\log^{3/2} OPT)$, where $OPT$ is the size of an optimal solution on general undirected graphs.
\end{itemize}
Finally, we obtain polynomial kernels for the case when $\cal F$ only contains graph $\theta_c$

as a minor for a fixed integer $c$. The graph $\theta_c$
consists of two
vertices connected by $c$ parallel edges. Even though this may appear to be a very restricted class
of problems it already encompasses well-studied problems such as {\sc Vertex Cover}, {\sc Feedback Vertex Set} and \textsc{Diamond Hitting Set}
.
The generic kernelization algorithm is based on a non-trivial application of protrusion techniques, previously used only for problems on
topological graph classes.
