WebThere is a natural way to push forward currents (by duality with the pull-back of smooth forms). Furthermore, the De Rham cohomology for currents is (naturally) isomorphic to the one of smooth forms. Therefore, you can push forward a smooth class considering it a current class, and using then the previous natural isomorphism.
