Eugenio Elia Levi (18 October 1883 – 28 October 1917) was an Italian mathematician, known for his fundamental contributions in group theory, in the theory of partial differential operators and in the theory of functions of several complex variables: he was the younger brother of Beppo Levi and died in the First World War.
Work
Research activity
He wrote 33 papers, classified by his colleague and friend Mauro Picone[1] according to the scheme reproduced in this section.
Differential geometry
Group theory
He wrote only three papers in group theory: in the first one, Levi (1905) discovered what is now called Levi decomposition, which was conjectured by Wilhelm Killing and proved by Élie Cartan in a special case.
Function theory
In the theory of functions of several complex variables he introduced the concept of pseudoconvexity[2] during his investigations on the domain of existence of such functions: it turned out to be one of the key concepts of the theory.
Cauchy and Goursat problems
Boundary value problems
His researches in the theory of partial differential operators lead to the method of the parametrix, which is basically a way to construct fundamental solutions for elliptic partial differential operators with variable coefficients: the parametrix is widely used in the theory of pseudodifferential operators.

Notes
- ^ This section is mainly based on the survey (Picone 1959), included in Levi's "Opere (Collected works)" and describing his researches briefly but comprehensively; occasionally, also the comments of Guido Fubini in reference (Fubini & Loria 1917) are taken into account.
- ^ See the two well known papers (Levi 1910) and (Levi 1910): note that Levi deals with functions of two complex variables, but his calculations can be extended to functions with any finite number of variables, as he explicitly states. Note also that Levi, following a then well established practice, does not uses Wirtinger derivatives.
