This volume contains the proceedings of the 11th International
Symposium on Orthogonal Polynomials, Special Functions, and their
Applications, held August 29–September 2, 2011, at the Universidad
Carlos III de Madrid in Leganés, Spain.

The papers cover asymptotic properties of polynomials on curves of
the complex plane, universality behavior of sequences of orthogonal
polynomials for large classes of measures and its application in
random matrix theory, the Riemann–Hilbert approach in the study of
Padé approximation and asymptotics of orthogonal polynomials,
quantum walks and CMV matrices, spectral modifications of linear
functionals and their effect on the associated orthogonal polynomials,
bivariate orthogonal polynomials, and optimal Riesz and logarithmic
energy distribution of points. The methods used include potential
theory, boundary values of analytic functions, Riemann–Hilbert
analysis, and the steepest descent method.

#### Readership

Graduate students and research mathematicians interested in special functions and orthogonal polynomials.
