제목: Combinatorics around two extensions of Hermite polynomials
초록:
    We will highlight two examples of the interplay of combinatorics and 
orthogonal polynomials by considering two recent one-parameter extensions of Hermite polynomials: 
a curious q-analog in connection with q-Weyl algebra and the 2D-Hermite polynomials.
As application we derive a generalization of Touchard-Riordan formula for 
crossings of chords joining pairs of 2n points on a circle and a new Kibble-Slepian type 
formula for the 2D-Hermite polynomials, which extends the Poisson kernel for these polynomials.
