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 $…

Universal homomorphisms, universal structures, and the polymorphism clones of homogeneous structures
Christian Pech, Maja Pech
Using a categorial version of Fraïssé's theorem due to Droste and Göbel, we derive a criterion for a comma-category to have universal homogeneous objects. As a first application we…
