Chromatic Feature Vectors for 2-Trees: Exact Formulas for Partition Enumeration with Network Applications
J. Allagan, G. Morgan, S. Langley +2
We establish closed-form enumeration formulas for chromatic feature vectors of 2-trees under the bichromatic triangle constraint. These efficiently computable structural features d…

Golden Ratio Growth and Phase Transitions in Chromatic Counts of Circular Chord Graphs
Rogelio N. Lopez-Bonilla, Julian Allagan, Shawn M. Langley +1
We study generalized circular chord graphs , formed from a cycle by adding fixed-offset chords of length and, for even , diameters. Using transfer…
