(16.03.1846
- 07.07.1927)**
**
**
**
****Outstanding
Swedish mathematician.**
**
Born in the family of Ph.D. Juhan Olof Leffler and Klara Elementary
School teacher in Stockholm.** **He
was the youngest son, but Fritz, the future professor of northern
languages, grew up in the family, and the third child was Anna
Charlotte, later the famous Swedish writer.**
**
The boy showed early mathematical ability.** **In
Klara’s school, he did mathematics 3 classes higher than his own
class, and then, in the gymnasium, he was generally freed from
mathematics.** **He
studied himself, he studied the works of Cauchy.** **Gustav
continued his mathematical education at the University of Uppsala
and graduated in 1872 with the academic title of Doctor of
Philosophy.** **In
1873 he received a Byzantine scholarship to travel abroad for three
years and to replenish his education.** **Once
Mittag-Leffler said that the greatest influence on him was the work
of two mathematical geniuses - Abel and Galois.** **Both
lived a short life and left the greatest mathematical legacy.** **Abroad,
Mittag-Leffler was most impressed by the lectures of Karl
Weierstrass.** **The
teacher and the student found each other.** **And
in the future, Karl Weierstrass was attentive to his Swedish
student, followed his mathematical work, congratulated his colleague
on the basis of the journal Acta mathematica.**
**
Mittag-Leffler went to work in Helsingfors (Helsinki).** **The
competition for the post of professor of mathematics was attended by
five people.** **Mittag-Leffler
was recognized as the most educated mathematically and creatively
minded.**
**
At that time, the university was taught in Swedish, since Finland
was part of Sweden.** **When
she became part of Russia, the Finns awoke national feelings.** **The
country was very strong nationalist sentiment.** **At
the University of Magnus Mittag-Leffler, 11 votes were cast against
9, and in May 1877 he was appointed as a professor and began to
lecture.** **At
first, nationally-minded Finnish students could not forgive Gustav
Mittag-Leffler for being a Swede.**
**
The professor treated students with great sympathy, clearly gave
lectures, the subject was stated precisely and strictly, like a real
Weierstrass student.** **In
Helsingfors, he met the beautiful and charming, cheerful Signe Julia
Emilia, the daughter of General Julius Jacob Lindfors.** **They
got married and lived a long life, although the relationship with
their relatives Signe evolved difficult.** **About
this scientist wrote to
Sofia Kovalevskaya.** **The
great mathematicians had a tender and faithful friendship.**
**
After Helsingfors Mittag-Leffler moved to Stockholm, where he
worked first as a professor at the Higher School and then as its
rector.** **He
considered the main business of his life the foundation of the
international mathematical journal "Acta mathematica", in which
articles of outstanding mathematicians were published.** **He
invited to collaborate in the magazine and Sofia Kovalevskaya.** **By
the way, Gustav Mittag-Leffler carefully preserved all
correspondence with Kovalevskaya, their letters are kept in the
institute bearing his name.**
**
He created a mathematical school in Stockholm, he had many students.** **Scientific,
organizational and social activities were simply awesome.** **He
was sick a lot, but did not stop working for a minute.** **His
main work relates to the theory of analytic functions.**
**
Magnus Gustav Mittag-Leffler lived a great life, he was a member of
many academies of sciences.** **His
mathematical creativity in the form of theory, generalizations and
ideas contributed to the development of mathematics.** **In
Sweden, there is a mathematical institute of spouses Mittag-Leffler.** **Its
foundation dates back to 1880, when the mathematician purchased a
villa in the suburbs of Stockholm, which was substantially modified,
expanded and turned into a scientific center.** **In
1916, he sold part of the land due to financial losses in the
construction of a hydropower station on the Ume River. **
**
On the day of the 70th anniversary of Mittag-Leffler, the spouses
made a will according to which all their property, research center
and villa transferred to the new organization - the Mathematical
Institute of the Mittag-Leffler spouses.**
**
In 1927 the villa was visited by French mathematician Henri Weil
and stayed with Mittag-Leffler.** **He
admired the library, the museum.** **Gustav
seemed to Weil strong, but quite unexpectedly Magnus Gustav
Mittag-Leffler died.**
