Dario Graffi (10 January 1905 – 28 December 1990) was an influential Italian mathematical physicist. He is known for his researches on the Electromagnetic field, particularly for a mathematical explanation of the Luxemburg effect, for proving an important uniqueness theorem for the solutions of a class of fluid dynamics equations including the Navier-Stokes equation,^[1] for his researches in continuum mechanics and for his contribution to oscillation theory.

Selected works

Graffi, Dario (1936), "Una teoria ereditaria dell'effetto Lussemburgo", Rendiconti del Seminario Matematico della Università di Padova (in Italian) 7: 36–54, JFM 62.0546.02, Zbl 0015.13705 . In the paper "An hereditary theory of the Luxemburg effect" (English translation of the title), written only few years after the discovery of the effect itself, Dario Graffi proposes a theory of the Luxemburg effect based on Volterra's theory of hereditary phenomena.
Graffi, Dario (1953), "Il Teorema di Unicita nella Dinamica dei Fluidi Compressibili", Journal of Rational Mechanics and Analysis (in Italian) 2 (1): 99–106, doi:10.1512/iumj.1953.2.52004, ISSN 0022-2518, MR 0052270, Zbl 0050.19604 . In the paper "The uniqueness theorem in the dynamics of compressible fluids" (English translation of the title) Graffi extends to compressible viscous fluids a uniqueness theorem for the solutions to Navier-Stokes equation in bounded domains, previously proved only for incompressible fluids by Emanuele Foà and rediscovered by David Dolidze.^[2]

In the paper "On the uniqueness theorem in fluid mechanics" (English translation of the title) Graffi extends his uniqueness theorem for the solutions of Navier-Stokes equations on unbounded domains relaxing previously assumed hypotheses on the behaviour of the velocity at infinity.
