    • A Review of Finite Approximations, Archimedean and Non-Archimedean 

      Digernes, Trond (Journal article; Peer reviewed, 2018)
      We give a review of finite approximations of quantum systems, both in an Archimedean and a non-Archimedean setting. Proofs will generally be omitted. In the Appendix we present some numerical results.

    • Finite approximations of physical models over local fields 

      Bakken, Erik Makino; Digernes, Trond (Journal article; Peer reviewed, 2015)
      We show that the Schrödinger operator associated with a physical system over a local field can be approximated in a very strong sense by finite Schrödinger operators. Some striking numerical results are included at the end ...
