# Adolf Kneser

### Born: 19 March 1862 in Grüssow,
Germany

Died: 24 Jan 1930 in Breslau, Germany (now
Wroclaw, Poland)

**Adolf Kneser** was taught by Kronecker
and also influenced by Weierstrass.
After writing a thesis on algebraic functions and equations, he worked on space
curves.

Kneser was appointed to the chair in Dorpat, and it was while
he was holding the chair there that his son Hellmuth
Kneser was born. Later Adolf Kneser was appointed to the chair of
mathematics at Breslau where he spent the rest of his career.

Adolf Kneser's main work was mainly in two areas. One area was
that of linear differential equations; in
particular he worked on the Sturm-Liouville
problem and integral equations in
general. He wrote an important text on integral equations. The second main area
of his work was the calculus of variations.

Wielandt,
writing in his obituary of Hellmuth
Kneser, describes Adolf Kneser as:-

*... the first to introduce *Hilbert*'s
new methods into analysis in his textbook on integral equations. He devoted
himself to the task of putting general results into concrete form by applying
them to the functions of mathematical physics. In a sense, he made the
boundary between the old and new mathematics his field of work.*
