Recognizing Circulant Graphs of Prime Order in Polynomial Time
A circulant graph G of order n is a Cayley graph over the cyclic group Zn. Equivalently, G is circulant iff its vertices can be ordered such that the corresponding adjacency matr...

The Induced Subgraph Order on Unlabelled Graphs
A differential poset is a partially ordered set with raising and lowering operators U and D which satisfy the commutation relation DU-UD = rI for some constant r. This notion may ...

Conditional Lexicographic Orders in Constraint Satisfaction Problems
The lexicographically-ordered CSP ("lexicographic CSP" for short) combines a simple representation of preferences with the feasibility constraints of ordinary CSPs. Prefe...
