WebThe hypercube graph Qn (for n > 1 ) : is the Hasse diagram of a finite Boolean algebra. is a median graph. Every median graph is an isometric subgraph of a hypercube, and can be formed as a retraction of a hypercube. has more than 22n-2 perfect matchings. (this is another consequence that follows easily from the inductive construction.)

WebOn the other hand, from Lemma 2.2, the eigenvalues of An are known to be √n,⋯,√n,−√n,⋯,−√n. Note that AH is a (2n−1 +1)× (2n−1 + 1) submatrix of the 2n × 2n matrix An. By Cauchy’s Interlace Theorem, λ1(AH) ≥ λ2n−1(An) = √n. Combining the two inequalities we just obtained, we have Δ(H) ≥ √n, completing the proof of our theorem. ∎ …
