Jens Franke is a German
mathematician
. He holds a chair at the University of Bonn
's Hausdorff Center for Mathematics
since 1992. Franke's research has covered various problems of number theory
, algebraic geometry
and analysis
on locally symmetric spaces.
Franke attended the University of Jena, where he earned his Ph.D. under Hans Triebel in 1986. He was awarded the EMS Prize in 1992, and the Oberwolfach Prize in 1993.
In recent years, Franke worked on an implementation of the Number Field Sieve algorithm for prime decomposition. In May 2007, he and his colleague Thorsten Kleinjung announced the factorization of M1039 (see also Mersenne prime
).

Algebraic geometry
Algebraic geometry is a branch of mathematics which combines techniques of abstract algebra, especially commutative algebra, with the language and the problems of geometry. It occupies a central place in modern mathematics and has multiple conceptual connections with such diverse fields as complex...
and analysis
Analysis
Analysis is the process of breaking a complex topic or substance into smaller parts to gain a better understanding of it. The technique has been applied in the study of mathematics and logic since before Aristotle , though analysis as a formal concept is a relatively recent development.The word is...
