WebDec 5, 2012 · The incomplete gamma-function is defined by the equation $$ I (x,y) = \int_0^y e^ {-t}t^ {x-1} \rd t. $$ The functions $\Gamma (z)$ and $\psi (z)$ are transcendental functions which do not satisfy any linear differential equation with rational coefficients (Hölder's theorem). The exceptional importance of the gamma-function in … The Hankel functions are used to express outward- and inward-propagating cylindrical-wave solutions of the cylindrical wave equation, respectively (or vice versa, depending on the sign convention for the frequency ). Using the previous relationships, they can be expressed as If α is an integer, the limit … See more Bessel functions, first defined by the mathematician Daniel Bernoulli and then generalized by Friedrich Bessel, are canonical solutions y(x) of Bessel's differential equation The most important … See more The Bessel function is a generalization of the sine function.
