- Abstract
- The Swedish mathematician Gösta Mittag-Leffler (1846-1927) is well-known for founding Acta Mathematica, the famous international mathematical journal. His mathematical contributions are connected chiefly with complex analysis. The Mittag-Leffler theorem which built on Karl Weierstrass' work asserts the existence of meromorphic function with prescribed poles and principal parts.
The main purpose of this thesis is to make a well-organised note of the Mittag-Leffler theorem which plays a significant role in complex analysis. The Weierstrass theorem which prescribes the zeros of holomorphic functions will be proved by using the result of the Mittag-Leffler's theorem. Moreover, the concept of the Mittag-Leffler star, a starshaped open domain...

The Swedish mathematician Gösta Mittag-Leffler (1846-1927) was one of the most influential researchers in Swedish mathematics. His mathematical contributions are connected chiefly with complex analysis. He studied with Karl Weierstrass while he travelled to Berlin and some of his research were built on Weierstrass' work, such as the Mittag-Leffler theorem which is the main topic of this paper.
The Mittag-Leffler theorem proves the existence of meromorphic functions with prescribed poles and principal parts. Interestingly, this study began as an extension of the Weierstrass theorem. As a continuation of Weierstrass's work, it was undertaken with the tools acquired from Weierstrass' lectures. These facts also show that Mittag-Leffler was indeed an important contributor to Weierstrass's research program concerning the foundations of analysis.
Mittag-Leffler published the final version of the theorem in 1884, in his newly-established journal Acta Mathematica which served as a comprehensive account of essentially all of his work on the subject. The theorem was seen as an important and fundamental element in complex analysis. It generated a number of research in the following generation of mathematicians, including the well-known figures Picard, Appell, and Poincaré, and it remained popular and widely-studied in different languages, such as French, Russian and German.
