A generalization of Schur functions: applications to Nevanlinna functions, orthogonal polynomials, random walks and unitary and open quantum walks
F. Alberto Grünbaum, Luis Velázquez
Recent work on recurrence in quantum walks has provided a representation of Schur functions in terms of unitary operators. We propose a generalization of Schur functions by extendi…

Linear spectral transformations of Carathéodory functions
M. J. Cantero, L. Moral, L. Velázquez
In this paper we present some recent results concerning linear spectral transformations of Carathéodory functions. More precisely, given two Carathéodory functions related by a lin…

Second Order Formalism for fermions: Anomalies and Species doubling on the Laticce
J. L. Cortés, J. Gamboa, L. Velázquez
A new formulation for fermions on the lattice based on a discretization of a second order formalism is proposed. A comparison with the first order formalism in connection with the…
