Efficient reversal of transductions of sparse graph classes
Jan Dreier, Jakub Gajarský, Michał Pilipczuk
(First-order) transductions are a basic notion capturing graph modifications that can be described in first-order logic. In this work, we propose an efficient algorithmic method to…

Elementary first-order model checking for sparse graphs
Jakub Gajarský, Michał Pilipczuk, Marek Sokołowski +2
It is known that for subgraph-closed graph classes the first-order model checking problem is fixed-parameter tractable if and only if the class is nowhere dense [Grohe, Kreutzer, S…
