Spectral decimation of piecewise centrosymmetric Jacobi operators on graphs
Gamal Mograby, Radhakrishnan Balu, Kasso A. Okoudjou +1
We study the spectral theory of a class of piecewise centrosymmetric Jacobi operators defined on an associated family of substitution graphs. Given a finite centrosymmetric matrix…

Spectral decimation of a self-similar version of almost Mathieu-type operators
Gamal Mograby, Radhakrishnan Balu, Kasso A. Okoudjou +1
We introduce self-similar versions of the one-dimensional almost Mathieu operators. Our definition is based on a class of self-similar Laplacians instead of the standard discrete L…
