Martin Widmer

Martin Widmer is a Professor specializing in Number Theory. His research focuses on advanced topics in algebraic and analytic number theory, particularly generators of number fields, height functions, and Northcott properties. He maintains an active publication record with 26 research outputs, including articles and preprints in journals like Forum Mathematicum and Acta Arithmetica.

His core research explores:

• Constructive aspects of number fields (generators, integral bases)
• Distribution properties of algebraic numbers via heights
• Extensions of the Northcott theorem to infinite fields
• Connections between Diophantine approximation and arithmetic geometry

He has led two collaborative research projects funded by the London Mathematical Society:

• Joint Research Groups in the UK (Dec 2019 – Nov 2021): Fostered interdisciplinary number theory collaborations.
• Research in Pairs (Oct–Nov 2019): Intensive short-term collaboration on emerging problems.

Widmer has supervised at least one graduate student, though specific details are undisclosed.
