Welcome to the Algebra and Number Theory group at the University of Copenhagen!
The research group 'Algebra and number theory' is involved with a broad section of modern algebra, algebraic geometry, and number theory.
We organize a regular seminar: Number Theory Seminar.
We are an active node in the Nordic Number theory Network: www.ncube.net.
Here is a list of the members of the group together with brief descriptions of their fields:
Core:
 Lars Halvard Halle: Algebraic and arithmetic geometry; curves, abelian varieties, CalabiYau varieties, zeta functions, motivic integration, degenerations, Hilbert schemes and moduli spaces.
 Lars Hesselholt: Ktheory, algebraic geometry, algebraic topology, number theory.
 Henrik Holm: Homological algebra and its areas of application, including representation theory, ring theory, and category theory.
 Ian Kiming: Algebraic number theory and arithmetic geometry, in particular Galois representations and automorphic forms, classical, mod p, and padic aspects.
 Mehdi Fabien Pazuki: Number theory, diophantine geometry, heights, elliptic curves, abelian varieties, rational points on curves.
 Morten S. Risager: Analytic number theory and automorphic forms.
Postdocs:
 Daniel Bergh: Algebraic geometry.
 Linda Karina Frey: Number theory, elliptic curves, (CM) Jacobians of genus 2 curves, heights.
 Cody Gunton: Arithmetic geometry, especially integral padic Hodge theory and the theory of degenerations.

Farbod Shokrieh: The intersection of nonarchimedean (and tropical) geometry, algebraic geometry, number theory, and combinatorics.
PhD students:
 Francesco Campagna: Algebraic number theory with a focus on elliptic curves with complex multiplication (PhD with Pazuki).
 Asbjorn Nordentoft: Analytic number theory (phD with Risager).
 Luigi Pagano: Algebraic Geometry (PhD with Lars Halle).

Riccardo Pengo: Lfunctions, in particular relationships between Mahler measures and derivatives of Lfunctions (PhD with Pazuki and Kiming).
Emeriti:

Christian U. Jensen: Algebraic number theory with a particular view towards Galois theoretic embedding problems.
 Søren Jøndrup: Noncommutative ring theory, in particular P.I. theory with applications to finitedimensional representations of noncommutative rings.
