First-order interpretations of bounded expansion classes

J Gajarský, S Kreutzer, J Nešetřil… - ACM Transactions on …, 2020 - dl.acm.org
The notion of bounded expansion captures uniform sparsity of graph classes and renders
various algorithmic problems that are hard in general tractable. In particular, the model …

Rankwidth meets stability

J Nešetřil, PO Mendez, M Pilipczuk, R Rabinovich… - Proceedings of the 2021 …, 2021 - SIAM
We study two notions of being well-structured for classes of graphs that are inspired by
classic model theory. A class of graphs is monadically stable if it is impossible to define …

Indiscernibles and flatness in monadically stable and monadically NIP classes

J Dreier, N Mählmann, S Siebertz… - arxiv preprint arxiv …, 2022 - arxiv.org
Monadically stable and monadically NIP classes of structures were initially studied in the

Clique-width for hereditary graph classes

Clustering powers of sparse graphs

J Nešetřil, PO de Mendez, M Pilipczuk… - arxiv preprint arxiv …, 2020 - arxiv.org
We prove that if $ G $ is a sparse graph---it belongs to a fixed class of bounded expansion
$\mathcal {C} $---and $ d\in\mathbb {N} $ is fixed, then the $ d $ th power of $ G $ can be …
