On flat extended grids
No full textA family of flat flag-transitive extended grids was constructed in Meixner and Pasini (1993). In fact, those extended grids are instances of the gluing construction described in Buekenhout et al. (1994). They can be obtained by gluing a circular space with 2n points with a dual grid of order (1,2n - 2). In this paper we shall prove that all flat flag-transitive extended grids but the emi-octahedron can be obtained as gluings in that way
Recurrence coefficients for discrete orthonormal polynomials and the Painlevé equations
No full textWe investigate semi-classical generalizations of the Charlier and Meixner polynomials, which are discrete orthogonal polynomials that satisfy three-term recurrence relations. It is shown that the coefficients in these recurrence relations can be expressed in terms of Wronskians of modified Bessel functions and confluent hypergeometric functions, respectively for the generalized Charlier and generalized Meixner polynomials. These Wronskians arise in the description of special function solutions of the third and fifth Painlevé equations

A family of multiply extended grids
No full textWe construct an infinite family {Gamma(n)}(n=5) of finite connected graphs Gamma(n) that are multiple extensions of the well-known ''extended grid'' discovered in [1] (which is isomorphic to Gamma(5)). The graphs Gamma(n) are locally Gamma(n-1) for n > 5, and have the following property: the automorphism group G(n) of Gamma(n) permutes transitively the maximal cliques of Gamma(n) (which are n-cliques) and the stabilizer of some n-clique x of Gamma(n) in G(n) induces Sigma(n) on the vertices of pi. Furthermore we show that the clique complexes of the graphs Gamma(n) are simply connected
The Meixner process : theory and applications in finance
No full textThe Meixner process is a special type of Levy process which origi-nates from the theory of orthogonal polynomials. It is related to the Meixner-Pollaczek polynomials by a martingale relation. We discuss sev-eral properties of the Meixner process. We apply the Meixner process to nancial data. First, we shows that the Normal distribution is a very poor model to t log-returns of nancial assets like stocks or indices. In order to achieve a better t we replace the Normal distribution by the more sophisticated Meixner distribution, taking into account, skewness and excess kurtosis. We show that the underlying Meixner distribution allows a much better t to the data by performing a number of statistical tests. Secondly, we introduce stock price models based on the Meixner process in order to price nancial derivatives. A rst signicant improvement can be achieved with respect to the famous Black-Scholes model (BS-model) by replacing its Brownian motion by the more
exible Meixner process. However, there still is a discrepancy between market and theoretical prices. The main feature which these Levy models are missing is the fact that volatility or more generally the environment is changing stochastically over time. By making business time stochastic, an idea which was developed in [9], one can incorporate these stochastic volatility eects. The resulting option prices can be calibrated almost perfectly to empirical prices. 2
