Topological gauge fixing

International audienceWe implement the metric-independent Fock-Schwinger gauge in the abelianquantum Chern-Simons field theory defined in ${\mathbb R}^3$. The expressionsof the various components of the propagator are determined. Although the gaugefield propagator differs from the Gauss linking density, we prove that itsintegral along two oriented knots is equal to the linking number
