  1. Gosta Mittag-Leffler Jason Gentry

  2. Life at Home • Mittag-Leffler was born in Stockholm on March 16, 1846 • Father was a high school teacher/principal • Born in the schoolhouse where his father taught • Sister was writer • Only one to add his mother’s maiden name, Mittag, to his name

  3. Education • Entered Uppsala University in 1865, studying mathematics • Appointed as a Docent in 1872 • Was endowed with a conditional salary: studying abroad for three years • Left for Paris in October 1873

  4. Education Travels • Main goal of the Paris trip was to learn from Hermite. • Went to Berlin in the spring of 1875 • While in Berlin, attended Weierstrass’ lectures • Appointed to a chair at the University of Helsinki in 1876 • 5 years later, returned home to become the first holder of the mathematics chair at Stockholm University

  5. Member of: • Royal Swedish Academy of Sciences • Finnish Society of Sciences and Letters • Royal Swedish Society of Sciences in Uppsala • Royal Physiographic Society in Lund • Royal Society of London • Academie des Sciences in Paris • Held honorary doctorates from several universities, including Oxford

  6. Mittag-Leffler Star • Used in Complex Mathematics • The 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

  7. 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
