Locally semicomplete digraphs: A generalization of tournaments
In this paper we introduce a new class of directed graphs called locally semicomplete digraphs. These are defined to be those digraphs for which the following holds: for every vertex x the vertices dominated by x induce a semicomplete digraph and the ...

New tools for the construction of directed strongly regular graphs: Difference digraphs and partial sum families [PDF]
We define a class of digraphs involving differences in a group that generalizes Cayley digraphs, that we call difference digraphs. We define also a new combinatorial structure, called partial sum family, or PSF for short, from which we obtain difference ...

On the structure of oriented graphs and digraphs with forbidden tournaments or cycles [PDF]
Motivated by his work on the classification of countable homogeneous oriented graphs, Cherlin asked about the typical structure of oriented graphs (i) without a transitive triangle, or (ii) without an oriented triangle.

Generalizations of tournaments: A survey
We survey results concerning various generalizations of tournaments. The reader will see that tournaments are by no means the only class of directed graphs with a very rich structure.
