    The recursive algorithm to construct Dirichlet function by A. N. Lysiuk, S. S. Derechennik

    Published 2019-06-01
    “…The importance of this problem is demonstrated for the procedures processing statistical data, representing the ratio of two discrete variables with a variable denominator. It is found out, that that required number of fractions is equal to the Dirichlet function value at the x point, and the original rule is proposed to construct it, which has a simple geometric interpretation. …”
