Abstract:

We study the validity of an extension of Frobenius theorem on integral manifolds for some classes of Pfaff-type systems of partial differential equations involving multidimensional rough'' signals, i.e.\ differentials'' of given H\"{o}lder continuous functions interpreted in a suitable way, similarly to Young Differential Equations in Rough Paths theory. This can be seen as a tool to study solvability of exterior differential systems involving rough differential forms, i.e.\ the forms involving weak (distributional) derivatives of highly irregular (e.g.\ H\"{o}lder continuous) functions; the solutions (integral manifolds) being also some very weakly regular geometric structures.
