Resumen de Phase structure and asymptotic zero densities of orthogonal polynomials in the cubic model

Gabriel Álvarez Galindo, Luis Martínez Alonso, Elena Blanca Medina Reus

• We apply the method we have described in a previous paper (2013) to determine the phase structure of asymptotic zero densities of the standard cubic model of non-Hermitian orthogonal polynomials. We provide a complete description of the two phases: the one cut phase and the two cut phase, and analyze the phase transition processes of the types: splitting of a cut, birth and death of a cut.
