          <dc:description>We investigate the parameterized complexity of generalisations and variations&#13;
of the dominating set problem on classes of graphs that are nowhere dense.  In&#13;
particular, we show that the distance-$d$ dominating-set problem, also known&#13;
as the $(k,d)$-centres problem, is fixed-parameter tractable on any class that&#13;
is nowhere dense and closed under induced subgraphs.  This generalises known&#13;
results about the dominating set problem on $H$-minor free classes, classes&#13;
with locally excluded minors and classes of graphs of bounded expansion.  A&#13;
key feature of our proof is that it is based simply on the fact that these&#13;
graph classes are uniformly quasi-wide, and does not rely on a structural&#13;
decomposition.  Our result also establishes that the distance-$d$&#13;
dominating-set problem is FPT on classes of bounded expansion, answering a&#13;
question of Ne{\v s}et{\v r}il and Ossona de Mendez.</dc:description>
