Query: Some adjacency-invariant spaces on products of short cycles   We study certain spaces of vertex functions on the Cayley graphs
corresponding to N-fold products of the group of integers modulo m, where m=3,
4, or 5, that are invariant under the adjacency operator that maps a value at a
given vertex to each of its neighbors. An application to spatio-spectral
limiting, an analogue of time and band limiting, is also discussed.
