A remark on the construction of off-shell propagators
Description
We discuss the construction of ''off-shell'' scattering amplitudes. Riemann surfaces with holes and their properties are briefly reviewed with the help of their doubles. We particularly concentrate on the conditions to impose on the boundary. In the particularly easy case of the tree propagator (the cylinder) we carry on the computation to give an explicit example of our ideas. (orig.)
