DiMaI - Dipartimento di Matematica e Informatica "Ulisse Dini"

The researches carried out by this group cover problems of great interest in contemporary Geometry, Analysis and Topology of Real and Complex Manifolds. The specific issues that are object of the researches belong to several fields such as Complex Analysis, Function Theory, Complex Differential Geometry, Algebraic Geometry, and their applications.

Part of the research program aims at studying methods of symbolic computation, in order to identify and verify significant results in some of the subjects and, at the same time, in order to draw the attention to the computational tools used.

Training through research is a fundamental part of the activity.
