The Dynamic Complexity of Acyclic Hypergraph Homomorphisms,show that an answer to this problem can be maintained under single-edge changes of ., as long as it stays acyclic, in the . framework of Patnaik and Immerman that uses updates expressed in first-order logic. If additionally also changes of . are allowed, we show that it is unlikely that existence of homomorphisms can be maintained in ..

,On the Parameterized Complexity of the Connected Flow and Many Visits TSP Problem,the capacities and induces a (strongly) connected subgraph. This generalizes previously studied problems like the ...We study the parameterized complexity of . parameterized by |.|, the treewidth . and by vertex cover size . of . and provide: .To achieve some of our results, we significantly extend an approach by Kowalik et al. .

This approach enables us to quickly obtain low-depth decompositions of very large graphs.
