Weighted spanning trees on some self-similar graphs.
W-graphs of representations of symmetric groups
Which Cayley graphs are integral?
Word distance on the discrete Heisenberg group
We establish an exact formula for the word distance on the discrete Heisenberg group ℍ₃ with its standard set of generators. This formula is then used to prove the almost connectedness of the spheres for this distance.
Words with intervening neighbours in infinite Coxeter groups are reduced.
