Tangent spaces and tangent bundles for diffeological spaces
J. Daniel Christensen, Enxin Wu
We study how the notion of tangent space can be extended from smooth manifolds to diffeological spaces, which are generalizations of smooth manifolds that include singular spaces a…

Homological Algebra for Diffeological Vector Spaces
Enxin Wu
Diffeological spaces are natural generalizations of smooth manifolds, introduced by J.M.~Souriau and his mathematical group in the 1980's. Diffeological vector spaces (especially f…

Categorical frameworks for generalized functions
Paolo Giordano, Enxin Wu
We tackle the problem of finding a suitable categorical framework for generalized functions used in mathematical physics for linear and non-linear PDEs. We are looking for a Cartes…
