Sfaccettature dello spazio-tempo nella relatività generale: il calcolo di Regge

One of the most innovative and fruitful contribution to theoretical physics by Tullio Regge (1931-2014) is presented. Known as “Regge Calculus”, it consists of a formulation of the General Relativity developed in the
celebrated paper “General Relativity without Coordinates”, published in 1961 in the Nuovo Cimento.
