From: Dick Askey (askey@math.wisc.edu)

Subject: **Death of Louis Auslander
**

Louis Auslander died at 68 on February 25, 1997. His early work was
on differential geometry. Later he worked on nilpotent Lie groups, and
this led to the study of theta functions. Two of his books are "Abelian
Harmonic Analysis, Theta Functions and Function Algebras on a
Nilmanifold", Springer, 1975, and "Lecture Notes on Nil-Theta Functions",
CBMS lectures published by American Mathematical Society, 1977. His later
work was on finite Fourier transforms, which also involves some special
functions. His expository paper with Tolimieri: "Is computing the finite
Fourier transform pure or applied mathematics?", BAMS (New Series), 1
(1979) 847-897, has been cited frequently, and is worth reading. The
first of the books mentioned above is also joint with Richard Tolimieri.

Auslander attended the Oberwolfach meeting on special functions and
group theory run by Askey, Koornwinder and Schempp in 1983. He was
fascinated by some of the work described there, as were some of us by
his work.
