Stefano Barbero

Stefano Barbero is an Assistant Professor at the Department of Mathematics, University of Trento. His research focuses on Number Theory, Algebra, and Combinatorics with applications to p-adic analysis, linear recurrence sequences, and Diophantine approximation. He has contributed to studies on continued fractions in p-adic contexts and algebraic structures of sequences.

His work frequently intersects with topics like divisibility sequences, Salem numbers, and combinatorial properties of algebraic structures such as Hurwitz series rings and binomial convolutions. He has collaborated extensively with researchers like Nadir Murru and Umberto Cerruti, producing influential papers in journals like Experimental Mathematics and Mathematics of Computation.

Key research directions include exploring periodic representations of quadratic irrationals in p-adic fields, developing matrix-based approximation methods for algebraic irrationalities, and investigating connections between group theory and Pythagorean triples via conic geometries.
