For example, you could specify Dirichlet boundary conditions for the interval domain [a, b], giving the unknown at the endpoints a and b. Dirichlet was German, but the name comes from French, which suggests but does not prove that Dirichlet himself would have pronounced the “CH” in the French manner. The Mobius function is an integer-valued function defined on the natural numbers as follows. This is useful, for example, for distributions where the normalization constant is difficult or expensive to compute. Add your entry in the Collaborative Dictionary.

In mathematics, the Laplace operator or Laplacian is a differential operator given by the divergence of the gradient of a scalar function on Euclidean space.It is usually denoted by the symbols , (where is the nabla operator), or .In a Cartesian coordinate system, the Laplacian is given by the sum of second partial derivatives of the function with respect to each independent variable. Dirichlet: Specifies the function’s value on the boundary. We give two alternative definition of the Dirichlet-to-Neumann map. Dirichlet principle.

This is in contrast to Dubins and Freedman [2], whose methods for choosing a distribution function on the interval [0, 1] lead with probability one to singular continuous distributions. Here, as the name indicates, the partition of a space follows the Dirichlet distribution. Subsequent work by Dirichlet, Riemann, Lebesgue, and others, throughout the next two hundred years, was needed to delineate precisely which functions were expandable in such trigonometric series.

In probability theory, Dirichlet processes (after Peter Gustav Lejeune Dirichlet) are a family of stochastic processes whose realizations are probability distributions.In other words, a Dirichlet process is a probability distribution whose range is itself a set of probability distributions. I am aware the name actually comes from Mr Dirichlet , a German scientist, and that the name should be pronounced as such -- but I'd like to have a US/UK version of the pronunciation too. It is a useful tool to construct and prove identities relating sums of arithmetic functions.
