Ilppo Simo Louhivaara

from Wikipedia, the free encyclopedia

Ilppo Simo Louhivaara (born October 29, 1927 in Helsinki , † December 19, 2008 ) was a Finnish mathematician.

Louhivaara studied mathematics at the University of Helsinki from 1945 and received his doctorate there in 1955 under Rolf Nevanlinna (About the first boundary value problem for the differential equation ). From 1955 he was in a Finnish working group that worked on the ESKO project for a computer. The computer was never finished, but IT experts were trained, who at that time also formed the core of the IBM subsidiary in Finland. 1958 to 1978 he was a professor at the University of Helsinki. In addition, from 1967 he was rector of the University of Jyväskylä , founded in 1965, where he was a professor and built up the mathematics faculty there before he became professor at the Free University of Berlin in 1977 .

Louhivaara dealt with analysis (existence and solution of boundary value problems in partial differential equations, for example (nonlinear) elliptic differential equations). He had good international contacts and published a lot in German. In Finland he organized satellite congresses for the international mathematicians' congresses in Stockholm (1962), Moscow (1966), Nice (1970) and Vancouver (1974) and was supposed to be the president of the ICM in Helsinki in 1978, but declined due to lack of time (he resigned his professorship at the Free University of Berlin).

In Germany he worked with Christian Simader (1943–2019), among others .
