In this work we study discrete analogues of an exact sequence vector bundles introduced by M. Atiyah in 1957, associated to any smooth principal $G$-bundle $\pi:Q\rightarrow Q/G$. the original setting, splittings correspond connections on bundle $\pi$. The that consider here can be studied two different categories: category fiber with a (chosen) section, FBS, and local Lie groupoids, lLgpdC. FB...
