Luigi Amerio (15 August 1912 – 28 September 2004), was an Italian electrical engineer and mathematician. He is known for his work on almost periodic functions, on Laplace transforms in one and several dimensions, and on the theory of elliptic partial differential equations.

Works

A selection of Luigi Amerio's scientific papers is published in the two volumes of his "Selecta" (Amerio 1990): he is also the author of several university textbooks and, jointly with his pupil Giovanni Prouse, he wrote the influential monograph on almost periodic functions (Amerio & Prouse 1971).

Amerio, Luigi (1943), "Su alcune questioni relative alla trasformazione di Laplace" [On some questions related to the Laplace transform], Istituto Lombardo di Scienze e Lettere, Rendiconti, Classe di Scienze Matematiche e Naturali, Serie III (in Italian), 76 (7): 191–216, MR 0011501, Zbl 0060.24909. In this work, Luigi Amerio proves an important theorem on Laplace transform.
