Algebra and Geometry
The scientific activities of the group traverse non-commutative algebra, combinatorics, representation theory, and various branches of geometry (algebraic, complex, differential, Kähler, projective, symplectic) often at the interface with mathematical physics.
Specific research interests include:
- Ring and nearring theory
- Infinite-dimensional Lie algebras
- Hopf algebras and quantum groups
- Integrable systems and homogeneous spaces
- Kähler Geometry
- Complex non-Kähler Geometry
- Deformation of complex structures
- Holomorphic dynamics
- Semi-Riemannian geometry
The Geometry group is a member of PRIN 2022 - Real and Complex Manifolds: Geometry and Holomorphic Dynamics. The local unit is coordinated by Adriano Tomassini.

a) Theory of nearrings. Study of specific classes of nearrings: for example Orthodox nearrings, A-rigid nearrings and weakly divisible nearrings. Such nearrings have provided a starting point for further study aimed at geometric-combinatorial structures (for example in building designs and codes from weakly divisible nearrings).
b) Theory of groups. Asymptotic problems and probabilistic methods.
Topic of research is to study the function P_G (t) that expresses the probability that t elements taken at random from a group G generate the same group. The function P_G can be expressed as Dirichlet series, and then extended by interpolation to a complex-valued function, the inverse of that function is called probabilistic zeta function of the group G.

Alberto SARACCO
My research is mainly in complex analysis, CR geometry and differential geometry.
More precisely, I have studied, under appropriate convex properties of domains in C^n (convexity, C-convexity, strictly and strongly pseudoconvexity): extension of functions and analytic objects; relation between the notion of Hilbert and Kobayashi hyperbolicity.
