Walter Borho

Walter Borho (born 17 December 1945, in Hamburg) is a German mathematician, who works on algebra and number theory. He is a professor at the University of Wuppertal.

Education
Borho received his PhD in 1973 from the University of Hamburg under the direction of Ernst Witt with a thesis titled Wesentliche ganze Erweiterungen kommutativer Ringe.

Research
Borho's research focuses on representation theory, Lie algebras, ring theory and also on number theory (amicable numbers) and tilings.

Awards and honors
In 1986 he was an invited speaker at the International Congress of Mathematicians in Berkeley (Nilpotent orbits, primitive ideals and characteristic classes – a survey).
