Summary, in English
We show that fixed-vertex subgraph homeomorphism for a pattern graph on p vertices and a host graph on n vertices can be solved in time O(2n − pnO(1)) or in time O(3n − pn6) and polynomial space. In effect, we obtain new non-trivial upper time-bounds on the exact complexity of the problem of finding k vertex-disjoint paths and general subgraph homeomorphism.
