A review of finite approximations, Archimedean and non-Archimedean. (English) Zbl 1457.81046
Summary: 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.
