The international conference on Differential Geometry of Fez will provide a forum and an excellent venue for researchers, academic faculty and students to present -and eventually publish- their research results and approaches. The ICDGFez2016 conference seeks original and high quality contributions in the fields chosen as topics for the the following three sections of this conference: $1$ Riemannian and pseudo-Riemannian manifolds and Submanifolds. $2$ Geometric Structures and Representation Theory. $3$ Geometric properties of functions and vector fields. The proceedings of the conference will be published as a special issue in the journal Note Di Matematica . All articles will undergo regular peer review procedure following the same high standards as for contributions to regular issues of the journal.
