Pekka Myrberg

Pekka Juhana MYRBERG ( born December 30, 1892 in Viipuri, † November 8, 1976 in Helsinki) was a Finnish mathematician. His specialty was the theory of functions. He was rector of the University of Helsinki.

MYRBERG in 1916 received his doctorate at the University of Helsinki at Ernst Lindelöf ( On the theory of convergence of Poincaré series). He taught first at a high school before he associate and later a professor at the University of Helsinki in 1921. In 1952 he was rector from 1952 to 1962 and Chancellor of the University of Helsinki. But retired in 1962, he published until the 1970s.

In the 1950s he published a series of seminal works on the iteration of rational functions in the complex domain and the real domain (in particular quadratic functions). He revived the investigation of new beginnings after Gaston Julia and Pierre Fatou early 20th century and is considered a forerunner of the period -doubling route to chaos, the Mitchell Feigenbaum examined in the late 1970s.

His doctoral include lauric MYRBERG and Kaarlo Virtanen.

He was a member of the Finnish Academy of Sciences. In 1942 he became a corresponding member of the Saxon Academy of Sciences. In 1954 he was invited speaker at the International Congress of Mathematicians in Amsterdam (On the integration of Poisson's equation on Riemann surfaces ).
