Some more notions of homomorphism-homogeneity
Deborah Lockett, John K. Truss
We extend the notion of 'homomorphism-homogeneity' to a wider class of kinds of maps than previously studied, and we investigate the relations between the resulting notions of homo…
Homogeneous coloured multipartite graphs
Deborah C Lockett, John K Truss
We classify the countable homogeneous coloured multipartite graphs with any finite number of parts. By Fraisse's Theorem this amounts to classifying the families F of pairwise non-…
Countable homogeneous lattices
A. Abogatma, J. K. Truss
We show that there are uncountably many countable lattices. We give a discussion of which such lattices can be modular or distributive. The method applies to show that certain othe…
Countable locally 2-arc-transitive bipartite graphs
Robert D. Gray, John K. Truss
We present an order-theoretic approach to the study of countably infinite locally 2-arc-transitive bipartite graphs. Our approach is motivated by techniques developed by Warren and…
