    Recurrence coefficients for discrete orthonormal polynomials and the Painlevé equations

    No full text
    We 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

    The Meixner process: Theory and applications in finance.

    Abstract The Meixner process is a special type of Lévy process which originates from the theory of orthogonal polynomials. It is related to the Meixner-Pollaczek polynomials by a martingale relation. We discuss several properties of the Meixner process. We apply the Meixner process to financial data. First, we shows that the Normal distribution is a very poor model to fit log-returns of financial assets like stocks or indices. In order to achieve a better fit 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 fit 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 financial derivatives. A first significant improvement can be achieved with respect to the famous Black-Scholes model (BS-model) by replacing its Brownian motion by the more flexible Meixner process. However, there still is a discrepancy between market and theoretical prices. The main feature which these Lévy 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 i

    The β-Meixner model

    We propose to approximate the Meixner model by a member of the B-family introduced in [Kuz10a]. The advantage of such approximations are the semi-explicit formulas for the running extrema under the B-family processes which enables us to produce more efficient algorithms for certain path dependent options
