On spectra of Laplacians on groups and graphs associated with group actions
We will discuss spectra of Laplacians on graphs and subshifts that arise naturally in the study of some interesting finitely generated groups, such as groups of intermediate growth and other self-similar groups. Interesting connections emerge with the spectral theory of Laplacians on fractals on one hand, and of Schroedinger operators on quasi-crystals on the other hand
