Decomposition of multivariate probabilities. An equivalent statement of Floquet's theorem is that Mathieu's equation admits a complex-valued solution of form. Pergamon Press. The notion of characteristic functions generalizes to multivariate random variables and more complicated random elements. December Identities of the latter type are useful for studying asymptotic properties of the modified Mathieu functions. Namespaces Article Talk. In mathematicsMathieu functions are solutions of Mathieu's differential equation.


  • In mathematics, Mathieu functions are solutions of Mathieu's differential equation. d 2 y d x 2 + In practice, Mathieu functions and the corresponding characteristic numbers can be readily calculated using Helmholtz equation can be interpreted as describing normal modes of an elastic membrane under uniform tension.

    To see how Mathieu functions arise in problems with elliptical boundary conditions, The esssential characteristics of this coordinate system are illustrated. ordinary Bessel functions Jn(x) and Yn(x), the R equation is called the modified. Mathieu functions, Mathieu differential equation, Mathieu characteristic In order to solve equation (1), it is normally separated into the following differential.

    Methods of Theoretical Physics: Pt. Oxford University Press. Moreover, unlike many other special functions, the solutions of Mathieu's equation cannot in general be expressed in terms of hypergeometric functions.

    The characteristic function provides an alternative way for describing a random variable. Mathieu's differential equations appear in a wide range of contexts in engineering, physics, and applied mathematics. The logarithm of a characteristic function is a cumulant generating functionwhich is useful for finding cumulants ; some instead define the cumulant generating function as the logarithm of the moment-generating functionand call the logarithm of the characteristic function the second cumulant generating function.

    Stability curves of the Mathieu equation as a function of 'a' and 'q'; our Scilab . characteristic exponent ν depends on a and q, and p(z) is a periodic function. equation (5) we can eliminate the recursion, obtaining ordinary differential equations.

    numerical evaluation of Mathieu functions and characteristic numbers. For nonzero q, the Mathieu functions are only periodic in z for certain values of a. Such characteristic values are given by the Wolfram Language functions.
    Characteristic functions are particularly useful for dealing with linear functions of independent random variables. This is not the case for the moment-generating function. December Namespaces Article Talk.

    The two approaches are equivalent in the sense that knowing one of the functions it is always possible to find the other, yet they provide different insights for understanding the features of the random variable.

    Higham; et al. Since Mathieu's equation is a second order differential equation, it always possesses two independent solutions.
