Mittag-Leffler Star

Used in Complex MathematicsThe Mittag-Leffler star of a complex-analytic function is a set in the complex plane.Obtained by extending a function along rays coming from a given point

Mittag-Leffler Star Cont.

A complex-analytic function f defined around some point a can be expanded in a series of polynomials which is convergent in the Mittag-Leffler star.

Each of the polynomials is a linear combination of the first several terms in the Taylor series expansion of function f around a point a.

The Mittag-Leffler expansion of function f is convergent in a larger set than the Taylor series of f
