Classification of thin Jordan schemes
Mikhail Muzychuk, Christian Pech, Andrew Woldar
Jordan schemes generalize association schemes in a similar way as Jordan algebras generalize the associative ones. It is well-known that association schemes of maximal rank are in…
The classification of homomorphism homogeneous oriented graphs
Bojana Pavlica, Christian Pech, Maja Pech
The modern theory of homogeneous structures begins with the work of Roland Fraïssé. The theory developed in the last seventy years is placed in the border area between combinatoric…
On a family of highly regular graphs by Brouwer, Ivanov, and Klin
Christian Pech, Maja Pech
Highly regular graphs for which not all regularities are explainable by symmetries are fascinating creatures. Some of them like, e.g., the line graph of W.~Kantor's non-classical $…
On highly regular strongly regular graphs
Christian Pech
In this paper we unify several existing regularity conditions for graphs, including strong regularity, -isoregularity, and the -vertex condition. We develop an algebraic comp…
