I defended my Ph.D. thesis at Stockholm University on 1966 December
03. My advisor there during the years 1961—1964 was
I attended his lectures on partial differential equations in the fall
of 1961 and the spring of 1962, and then his lectures on analytic
functions of several complex variables in the fall of 1962 and the
spring of 1963. During the academic year 1965-66, I was invited as a
Member at the Institute for Advanced Study in Princeton, NJ, and Lars
was there, so our relation could go on.
Lars Hörmander defended his Ph.D. thesis at Lund University on 1955
October 22. His advisor, as first registered in the Mathematics
Genealogy Project, was
Riesz was professor at Lund University and got his Ph.D. in 1912 at the
University of Budapest with
as advisor. Fejér got his Ph.D. at the
University of Budapest in 1902. His advisor was
Schwarz received his Ph.D. in 1864. His advisor was
His name was written Weierstrass in the nineteenth century and
nowadays most often Weierstraß.
Schwarz attended Weierstrass's lectures on Integral Calculus in 1861.
Weierstrass was awarded an honorary doctorate by the University of
Königsberg in 1854, so we cannot say he had a Ph.D. advisor. However,
he studied mathematics for Gudermann in 1838—1840. In a more recent
version of the Mathematics Genealogy
Project, Gudermann is considered to be the advisor of Weierstrass,
which makes it possible to go back to Gauss and Pfaff and even
Originally only Marcel Riesz was listed in the Mathematics Genealogy
Project as an advisor of Lars Hörmander, and I had followed this link
above. Later Lars Gĺrding (1919-03-07 — 2014-07-07) was
introduced as a second advisor. In a publication Lars Hörmander
"When I defended my thesis in 1955 Lars Gĺrding was my advisor for
Marcel Riesz had retired in 1953 and been in the US since then."

invited me to join him in Nice during the academic year 1967-68. He
influenced me a lot. I have tried to sum up my memories on him and our year together in a note
