Combinatorial classification of quantum lens spaces

Abstract

We answer the question of how large the dimension of a quantum lens space must be, compared to the primary parameter rr, for the isomorphism class to depend on the secondary parameters. Since classification results in C*-algebra theory reduces this question to one concerning a certain kind of SLSL-equivalence of integer matrices of a special form, our approach is entirely combinatorial and based on the counting of certain paths in the graphs shown by Hong and Szyma\'nski to describe the quantum lens spaces.
