Georges Julien Giraud[3] (22 July 1889[1] – 16 March 1943) was a French mathematician, working in potential theory, partial differential equations, singular integrals and singular integral equations:[4] he is mainly known for his solution of the regular oblique derivative problem and also for his extension to n–dimensional (n ≥ 2) singular integral equations of the concept of symbol of a singular integral, previously introduced by Solomon Mikhlin.[5]

  1. ^ a b According to the brief commemoration by Bertrand (1943b, p. 629): the "Georges Giraud" entry in the Enciclopedia Treccani states that he was born on 11 July 1889, and Tampieri (2014, p. 88) uses this source.
  2. ^ According to Bertrand (1943b, p. 629) and to the "Georges Giraud" entry in the Enciclopedia Treccani.
  3. ^ According to the year 1939 list of corresponding members of the "Geometry" section of the French Academy, this was his full name: however, he simply sign himself as "Georges Giraud" in all his scientific works.
  4. ^ See (Tricomi 1967, p. 21) and (Tampieri 2014, p. 89 and p. 90).
  5. ^ He announced his results in the short communication (Giraud 1936), without proof and acknowledging the previous work of Mikhlin. As a matter of fact, it was Mikhlin who gave the first proofs of these formulas, completing his work on the 2-dimensional theory: see (Mikhlin 1965, p. 9) or the entry "Singular integrals" for a comprehensive historical survey.
