As a particular form of this, he conjectured that a closed form is exact if it integrates to zero over any submanifold without boundary, and that a submanifold without boundary is itself a boundary of another submanifold, if every closed form integrates to zero

Poincaré, progress was slow as topology was a relatively new topic and access to the relevant literature was difficult in Lausanne. With the recommendation of Dumas, de Rham contacted Lebesgue and went to Paris for a few
