Eigenvalues of the Laplacian on the Goldberg-Coxeter constructions for $3$ - and $4$ -valent graphs

Toshiaki Omori, Hisashi Naito, Tatsuya Tate

We are concerned with spectral problems of the Goldberg-Coxeter construction for $3$ - and $4$ -valent finite graphs. The Goldberg-Coxeter constructions $GC_{k, l} (X)$ of a f…
