The QCD factorization theorem for diffractive processes in DIS is used to derive the leading twist contribution to the nuclear shadowing of partons due to the coherent projectile (photon) interactions with two nucleons (the low thickness limit). We calculate nuclear structure functions in the limit of large thickness (the black interaction limit). Based on the current analyzes of diffraction at...

We discuss the dynamics beyond topological hyperbolicity considering homeomorphisms satisfying shadowing property and generalizations of expansivity. It is proved that transitive countably expansive are in set points. This contrast with pseudo-Anosov diffeomorphisms two-dimensional sphere transitive, cw-expansive, satisfy but dynamical ball each point contains a Cantor subset. exhibit examples ...
