A note on the electromagnetic irradiation in a holed spatial region -- a space-time approach

We study the role of the topological homological property of a space-time with holes (a multiple connected manifold) on the formal solutions of the electromagnetic irradiation problem taking place on theses “holed” space-times. On three appendixes, additional to the bulk section 1, we also present important studies on this irradiation problem, now on others mathematical frameworks .
