We provide sufficient conditions for a mapping acting between two Banach spaces to be a diffeomorphism. Standart arguments allow us to obtain a local diffeomorphism. It is proved to be global using mountain pass geometry.

Since 100 years or so, it has been usually accepted that the conformal group could be defined in an arbitrary dimension n as the group of transformations preserving a non-degenerate flat metric up to a nonzero invertible point depending factor called

In this partly expository paper we give two applications of ideas from dynamical systems to the study of the injectivity properties of a polynomial local diffeomorphism F = ( F 1 , F 2 ) : R 2 → R 2 (by the work of Pinchuk, these maps need not be g

In this paper, the following assertion is proved: Let GW and $$ \tilde{GW} $$ be Grassmannian three-webs defined respectively in domains D and $$ \tilde{D} $$ of a Grassmannian manifold of straight lines of the projective space Pr+1; Φ : D → $$ \t

We establish sufficient conditions for a $$ {C}_c^1 $$ -local diffeomorphism between Frechet spaces to be a global diffeomorphism. We extend Clarke’s theory of generalized gradients to more general Frechet spaces. As a consequence, we define the Ch

A spherical periscope in multi-dimensional space is a system of two ideal mirrors that reflect the rays emanating from a fixed point to the rays coming back to the same point, and a reversed periscope is a system of two mirrors that reflect the rays

We develop some consequences of the connection between Calabi-Yau structures and torsion-free $G_2$ structures on compact and asymptotically cylindrical six- and seven-dimensional manifolds. Firstly, we improve the known proof that matching asymptoti
