Large random tilings of a hexagon

2025-09-15

Speaker: Arno Kuijlaars (KU Leuven, Belgium)

Large random tilings of a hexagon display the fascinating phenomenon of distinct asymptotic phases (frozen and rough, also referred to as solid and liquid), separated by a well-defined Arctic curve. In a weighted tiling model with periodically varying weights, a third phase (smooth, or...

Quasi-orthogonal polynomials and positive quadrature on the unit circle

2025-09-18

Speaker: Ruymán Cruz Barroso (University of La Laguna, Spain)

The concept of quasi-orthogonality was introduced in 1923 by M. Riesz in connection with moment problems, and then by L. Fejér and J.A. Shohat in 1933 and 1937 respectively, in the context or quadrature formulas.It is very well known that the polynomials that play a similar role on the unit...
