Quantum walks: Schur functions meet symmetry protected topological phases
C. Cedzich, T. Geib, F. A. Grünbaum +3
This paper uncovers and exploits a link between a central object in harmonic analysis, the so-called Schur functions, and the very hot topic of symmetry protected topological phase…

Tridiagonalization and the Heun equation
F. Alberto Grünbaum, Luc Vinet, Alexei Zhedanov
It is shown that the tridiagonalization of the hypergeometric operator yields the generic Heun operator . The algebra generated by the operators and is quadr…

The Quantum Walk of F. Riesz
F. A. Grunbaum, L. Velazquez
We exhibit a way to associate a quantum walk (QW) on the non-negative integers to any probability measure on the unit circle. This forces us to consider one step transitions that a…
