Entropy-Based Proofs of Combinatorial Results on Bipartite Graphs (2106.07336v1)
Published 14 Jun 2021 in cs.IT, math.CO, and math.IT
Abstract: This work considers new entropy-based proofs of some known, or otherwise refined, combinatorial bounds for bipartite graphs. These include upper bounds on the number of the independent sets, lower bounds on the minimal number of colors in constrained edge coloring, and lower bounds on the number of walks of a given length in bipartite graphs. The proofs of these combinatorial results rely on basic properties of the Shannon entropy.
