Arithmetic Chern-Simons theory names the attempt to apply constructions from Chern-Simons theory to the field of arithmetic, in view of patterns in the function field analogy. In particular, the papers (Kim1, Kim2) apply ideas of Dijkgraaf-Witten theory on 2+1 dimensional topological quantum field theory to arithmetic curves, that is, the spectra of rings of integers in algebraic number fields.

This theory pursues the surprising analogies between 3-dimensional topology and number theory, where knots embedded in a 3-manifold behave like prime ideals in a ring of algebraic integers, known as arithmetic topology.
