Halsey Royden

from Wikipedia, the free encyclopedia

Halsey Lawrence Royden Junior (born September 26, 1928 in Phoenix (Arizona) , † August 22, 1993 in Los Altos Hills ) was an American mathematician who dealt with function theory (complex analysis).

Royden studied at Phoenix College and from 1946 at Stanford University , where he completed his master's degree under Donald Spencer in 1949 . In 1951 he received his doctorate from Harvard University with Lars Ahlfors ( Harmonic functions on open Riemann surfaces ). He then went back to Stanford as an assistant professor (where the mathematics faculty was headed by Gabor Szegö ), where he became an associate professor of mathematics in 1953 and a full professorship in 1958. From 1962 to 1965 he was Deputy Dean of the School of Humanities and Sciences, from 1968/69 Acting Dean and from 1973 to 1981 Dean of the School of Humanities and Sciences. During this time, the Western Culture Program for undergraduates at Stanford was established in 1980 . He was also head of the mathematics faculty, for which he also worked as a historian.

He dealt with Riemann surfaces and their Teichmüller spaces, and later also with functional theory of several complex variables and complex differential geometry. His textbook Real Analysis has long been one of the standard works. He had been active in academic administration at Stanford since the 1950s (from 1956 as Assistant Executive Head of the Mathematics Faculty under Max Schiffer ) and was instrumental in the development of the mathematics curriculum at Stanford.

In 1970 he showed the equivalence of the Kobayashi metric with the Teichmüller metric on Teichmüller rooms.

He was a Guggenheim Fellow. In 1974 he was invited speaker at the International Congress of Mathematicians in Vancouver ( Intrinsic metrics on Teichmüller space ).

He was married to the mathematician Virginia "Jinx" Voegli and had two daughters and a son.
