About meNorwaythumb

I am a 3rd PhD student in number theory under the supervision of Alex Bartel. My interests include arithmetic geometry, representation theory and Galois representations.

Current Research Projects

  • I have some representation theoretic results which give a list of computable invariants which determine the isomorphism class of an arbitrary \mathbb{Z}_{(p)}[G]-lattices when G has cyclic Sylow p-subgroup. My results combine with existing work of Yakovlev with regulator constants. A report on this work is available here(PDF Document).
  • In some cases the above results can be applied relatively easily to lattices arising in number theory from unit groups of rings of integers or Mordell-Weil groups of abelian varieties. Hopefully some details of this will appear soon. This uses existing results of Bartel, Dokchitser-Dokchitser and Burns-Macias Castillo-Wuthrich.
  • More recently, I have been thinking about lifting decompositions of various cohomology theories to motives in the setting of universal abelian schemes over Shimura varieties.
