Basic Properties of Incomplete Macdonald Function with Applications

الملخص EN

The incomplete version of the Macdonald function has various appellations in literature and earns a well-deserved reputation of being a computational challenge.

This paper ties together the previously disjoint literature and presents the basic properties of the incomplete Macdonald function, such as recurrence and differential relations and series and asymptotic expansions.

This paper also shows that the incomplete Macdonald function, as a simple closed-form expression, is a particular solution to a parabolic partial differential equation, which arises naturally in a wide variety of transient and diffusion-related phenomena.
