For many practical purposes, a differential equation or other problem can be regarded as solved when its solutions can be expressed in terms of Bessel functions; it is also true when the solutions can be expressed in terms of any tabulated function, including the elementary trigonometric and ...
Bessel Function In subject area: Engineering Bessel functions, named after the German astronomer Friedrich Bessel, are defined as solutions of the Bessel differential equationx2d2ydx2+xdydx+(x2−α2)y=0, where α is a complex number. From: Transmutations, Singular and Fractional Differential ...

In Section 2, we briefly describe the transition probability derived from the Bessel stochastic differential equation. First Passage Time of a Markov Chain That Converges to Bessel Process In this section, one main result on the close-to-convexity of the generalized Bessel function with several cons...
A Bessel function Z_n(x) is a function defined by the recurrence relations Z_(n+1)+Z_(n-1)=(2n)/xZ_n (1) and Z_(n+1)-Z_(n-1)=-2(dZ_n)/(dx). (2) The Bessel functions are more frequently defined as solutions to the differential equation x^2(d^2y)/

special function, any of a class of mathematicalfunctionsthat arise in the solution of various classical problems ofphysics. These problems generally involve the flow of electromagnetic, acoustic, orthermal energy. Different scientists might not completely agree on which functions are to be included amo...
The Bessel function can also be defined by the contour integral (3) where the contour encloses the origin and is traversed in a counterclockwise direction (Arfken 1985, p. 416). The Bessel function of the first kind is implemented in the Wolfram Language as BesselJ[nu, z]. To solve...
