Roberto Marcolongo

Marco Roberto Longo ( born August 28, 1862 in Rome, † May 16, 1943 in Rome ) was an Italian mathematician who was known primarily for his work on vector analysis and theoretical physics.

He graduated in 1886 and later became an assistant to Valentino Cerruti ( 1850-1909 ) in Rome. In 1895 he became professor of classical mechanics at the University of Messina. In 1908 he went to the University of Naples Federico II, where he remained until his retirement in 1935.

He worked in the field of vector analysis with Cesare Burali - Forti, then known as " Italian notation ". In 1906 he wrote one of the first works that included a four-dimensional formalism for the representation of the relativistic invariance under Lorentz transformations. In 1921 he published together with Burali - Forti in Messina, a treatise on special and general relativity, where the absolute differential calculus was used without coordinates, in contrast to the representation of Tullio Levi -Civita and Gregorio Ricci - Curbastro.

He was a member of the Accademia Nazionale dei Lincei and other Italian academies.
