This is an announcement for the paper “Inversion of nonsmooth maps between Banach spaces” by Jesús A. Jaramillo<https://arxiv.org/find/math/1/au:+Jaramillo_J/0/1/0/all/0/1>, Sebastián Lajara<https://arxiv.org/find/math/1/au:+Lajara_S/0/1/0/all/0/1>, Óscar Madiedo<https://arxiv.org/find/math/1/au:+Madiedo_O/0/1/0/all/0/1>. Abstract: We study the invertibility nonsmooth maps between infinite-dimensional Banach spaces. To this end, we introduce an analogue of the notion of pseudo-Jacobian matrix of Jeyakumar and Luc in this infinite-dimensional setting. Using this, we obtain several inversion results. In particular, we give a version of the classical Hadamard integral condition for global invertibility in this context.
