Isospectral and not strongly isospectral spherical space forms with non-cyclic fundamental group
Mauro Colantonio
We construct the first examples of isospectral but not strongly isospectral spherical space forms with non-cyclic fundamental groups. We obtain infinitely many such pairs with isom…

The fundamental group of a spherical space form is not audible
Mauro Colantonio, Emilio A. Lauret
We revisit the problem of isospectral spherical space forms with non-cyclic fundamental groups after the works by Ikeda, Gilkey and Wolf. We find the first pair of spherical space…
