Snowflake groups, Perron-Frobenius eigenvalues and isoperimetric spectra
The k-dimensional Dehn (or isoperimetric) function of a group bounds the volume of efficient ballfillings of k-spheres mapped into kconnected spaces on which the group acts properly and cocompactly; the bound is given as a function of the volume of the sphere. We advance significantly the observed r...
