Id\`elic class field theory for 3-manifolds

Abstract

Following the analogies between 3-dimensional topology and number theory, we study an id\`elic form of class field theory for 3-manifolds. For a certain set $\mathcal{K}$ of knots in a 3-manifold $M$, we first present a local theory for each knot in $\mathcal{K}$, which is analogous to local class field theory, and then, getteing together over all knots in $\mathcal{K}$, we give an analogue of id\`elic global class field theory for an integral homology sphere $M$.
