Inner differentiability and differential forms on tangentially locally linearly independent sets

Aneta Velkoska, Zoran Misajleski


The de Rham theorem gives a natural isomorphism between De Rham cohomology and singular cohomology on a paracompact dierentiable manifold. We proved this theorem on a wider family of subsets of Euclidean space, on which we can define inner dierentiability. Here we define this family of sets called tangentially locally linearly independent sets, propose inner dierentiability on them, postulate
usual properties of dierentiable real functions and show that the integration over sets that are wider than manifolds is possible.
