He was born in
Acireale, a town near
Catania in Sicily, the elder of the four sons of Giuseppe Fichera and Marianna Abate.[1] His father Giuseppe was a professor of
mathematics and influenced the young Gaetano starting his lifelong passion. In his young years he was a talented
football player. On 1 February 1943 he was in the
Italian Army and during the
events of September 1943 he was taken prisoner by the
Nazist troops, kept imprisoned in
Teramo and then sent to
Verona: he succeeded in escaping from there and reached the Italian region of
Emilia-Romagna, spending with partisans the last year of war. After the war he was first in Rome and then in
Trieste, where he met Matelda Colautti, who became his wife in 1952.
His lifelong friendship with his teacher
Mauro Picone is remembered by him in several occasions. As recalled by
Colautti Fichera (2006, pp. 13–14), his father Giuseppe was an assistant professor to the chair of Picone while he was teaching at the
University of Catania: they become friends and their friendship lasted even when Giuseppe was forced to leave the academic career for economic reasons, being already the father of two sons, until Giuseppe's death. The young, in effect child, Gaetano, was kept by Picone in his arms. From 1939 to 1941 the young Fichera developed his research directly under the supervision of Picone: as he remembers, it was a time of intense work. But also, when he was back from the front in April 1945[5] he met Picone while he was in
Roma in his way back to
Sicily, and his advisor was so happy to see him as a father can be seeing its living child. Another
mathematician Fichera was influenced by and acknowledged as one of his teachers and inspirators was
Pia Nalli: she was an outstanding
analyst, teaching for several years at the University of
Catania, being his teacher of
mathematical analysis from 1937 to 1939.
Antonio Signorini and
Francesco Severi were two of Fichera's teachers of the Roman period: the first one introduced him and inspired his research in the field of
linear elasticity while the second inspired his research in the field he taught him i.e. the
theory of analytic functions of several complex variables. Signorini had a strong long-time friendship with Picone: on a wall of the
apartment building where they lived, in Via delle Tre Madonne, 18 in Rome, a memorial tablet which commemorates the two friends is placed, as
Fichera (1995b, p. 47) recalls. The two great mathematicians extended their friendship to the young Fichera, and as a consequence this led to the solution of the
Signorini problem and the foundation of the theory of
variational inequalities. Fichera's relations with Severi were not as friendly as with Signorini and Picone: nevertheless, Severi, which was one of the most influential Italian mathematicians of the first half of the 20th century, esteemed the young mathematician. During a course on the
theory of analytic functions of several complex variables taught at the
Istituto Nazionale di Alta Matematica from the fall of 1956 and the beginning of the 1957, whose lectures were collected in the book (
Severi 1958), Severi posed the problem of generalizing his theorem on the
Dirichlet problem for
holomorphic function of several variables, as
Fichera (1957, p. 707) recalls: the result was the paper (
Fichera 1957), which is a masterpiece, although not generally acknowledged for various reasons described by
Range (2002, pp. 6–11). Other scientists he had as teachers during the period 1939–1941 were
Enrico Bompiani,
Leonida Tonelli and
Giuseppe Armellini: he remembered them with great respect and admiration, even if he did not share all their opinions and ideas, as
Colautti Fichera (2006, p. 16) recalls.
The close friendship between
Angelo Pescarini and Fichera has not his roots in their scientific interests: it is another war story. As
Oleinik (1997, p. 12) recalls, Gaetano, being escaped from
Verona and hidden in a
convent in
Alfonsine, tried to get in touch with the local group of partisans in order to help the people of that town who had been so helpful with him: they were informed about an assistant professor to the chair of higher analysis in Rome who was trying to reach them. Angelo, which was a student of mathematics at the
University of Bologna under
Gianfranco Cimmino, a former pupil of
Mauro Picone, was charged of the task of testing the truth of Gaetano's assertions, examining him in mathematics: his question was:– "Mi sai dire una condizione sufficiente per scambiare un limite con un integrale (Can you give me a sufficient condition for interchanging limit and integration)?"–. Gaetano quickly answered:– "Non solo ti darò la condizione sufficiente, ma ti darò anche la condizione necessaria e pure per insiemi non-limitati (I can give you not only a sufficient condition, but also a necessary condition, and not only for bounded domains, but also for unbounded domains)"–. In effect, Fichera proved such a theorem in the paper (
Fichera 1943), his latest paper written in while he was in Rome before joining the army: from that moment on he often used to joke saying that good mathematicians can always have a good application, even for saving one's life.
One of his best friends and appreciated scientific collaborator was
Olga Arsenievna Oleinik: she cured the redaction of his last posthumous paper (
Fichera 1997), as
Colautti Fichera (2006, pp. 202–204) recalls. Also, she used to discuss his work with Gaetano, as he did with her: sometimes their discussion become lively, but nothing more, since they were extremely good friends and estimators of each one's work.
It is difficult to single out his contributions to functional analysis since, as stated at the beginning of this section, the methods of functional analysis are ubiquitous in his research: however, it is worth to remember paper (
Fichera 1955a), where an important existence theorem is proved.[10]
His contributions in the field of eigenvalue theory began with the paper (
Fichera 1955b), where he formalizes a method developed by
Mauro Picone for the approximation of eigenvalues of
operators subject only to the condition that their
inverse is
compact: however, as he admits in (
Fichera 1974a, pp. 13–14), this method does not give any estimate on the approximation error on the value of the calculated (approximated) eigenvalues.
His contributions to the theory of
exterior differential forms started as a war story:[18] having read a famous memoir of
Enrico Betti (where
Betti numbers were introduced) just before joining the army, he used this knowledge in order to develop a theory of
exterior differential forms while he was kept prisoner in
Teramo jail.[19] When he was back in Rome in 1945, he discussed his discovery with
Enzo Martinelli, who very tactfully informed him that the idea was already developed by mathematicians
Élie Cartan and
Georges de Rham. However, he continued work on this theory, contributing with several papers, and also advised all of his students to study it, despite from the fact of being an
analyst, as he remarks: his main results are collected in the papers (
Fichera 1961a) and (
Fichera 1961b). In the first one he introduced k-measures, a concept less general than
currents but easier to work with: his aim was to clarify the
analytic structure of currents and to prove all relevant results of the theory i.e. the
three theorems of de Rham and
Hodge theorem on harmonic forms in a simpler, more analytic way. In the second one he developed an abstract
Hodge theory, following the
axiomatic method, proving an abstract form of Hodge theorem.
his work in this field occupy all the volume (
Fichera 2002). He wrote bibliographical sketches for a number of mathematicians, both teachers, friends and collaborators, including
Mauro Picone,
Luigi Fantappiè,
Pia Nalli,
Maria Adelaide Sneider,
Renato Caccioppoli,
Solomon Mikhlin,
Francesco Tricomi,
Alexander Weinstein,
Aldo Ghizzetti. His
historical works contain several observations against the so-called historical revisitation: the meaning of this concept is clearly stated in the paper (
Fichera 1996). He identifies with the word revisitation the analysis of historical facts basing only on modern conceptions and points of view: this kind of analysis differs from the "true" historical one since it is heavily affected by the historian's point of view. The historian applying this kind of methodology to
history of mathematics, and more generally to the
history of science, emphasizes the sources that have led a field to its modern shape, neglecting the efforts of the pioneers.

Accademia Pontaniana in his "opere scelte" (
Fichera 2004) and in the volume (
Fichera 2002). These two references include most of the papers listed in this section: however, these volumes does not include his
monographs and
textbooks, as well as several survey papers on various topic pertaining to his fields of research.

Lax–Milgram theorem: as an application, the general existence and
uniqueness theorems of previous paper (
Fichera 1949) are proved dropping the hypothesis of
self-adjointness of the
linearpartial differential operators considered.
