EnglishWe consider a topological field theory in three space-time dimensions. We show that certain observables of this model can be used to define a topological invariant for a punctured Riemann surface. By means of the operator surgery method, we compute the value of this invariant for a Riemann surface of arbitrary genus and with an arbitrary number of colored punctures on it.
