Bäste Broder
Som korrekturet till Din brors afhandling ännu ej kommit mig till handa
har jag tänkt mig möjligheten att det kommit bort på posten och jag sänder
Dig därför ett nytt exemplar af samma korr. Vore tacksam om Du med
omgående ville göra i ordning detta korr. och skicka tillbaka till mig, vi
behöver trycka undan en del så att nya afhandlingar kunna sättas.
22 Johannes Malmquist (1882-1952), mathematician, the best student of Gösta Mittag-
Leffler in his last decade, professor at KTH 1913-1952, over a long period secretary of
Acta. Wrote jointly with Valdemar Stenström and Sture Danielson a 3 volume treatise
of analysis. In 1904 he gave a contribution to the theory of Mittag-Leffler’s E α -function
by constructing an entire function which goes to 0 on all rays through the origin except
the positive real axis. Otherwise, Malmquist’s research was mainly devoted to ordinary
differential equations in the complex domain. For instance, he studied the global theory
of first order equations of the type dy P (x, y)
= , where P, Q are polynomials without a
dx Q(x, y)
common divisor, to which problem he was inspired by Paul Painlevé’s lectures in Stockholm
in 1913. [], [52].
