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.

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. Giraud, Georges (29 June 1936), "Sur une classe générale d'équations à intégrales principales" [On a general class of principal integral equations], Comptes rendus hebdomadaires des séances de l'Académie des sciences (in French), 202, Paris: 2124–2127, JFM 62.0498.01, Zbl 0014.30903, available at Gallica. In this short note, Giraud extends (without proof) the formula for the composition of two 2-dimensional singular integral operators using their symbols, introduced shortly before by Solomon Grigor'evich Mikhlin, to higher dimensional singular integrals. Mikhlin, Solomon G. (1965), Multidimensional singular integrals and integral equations, International Series of Monographs in Pure and Applied Mathematics, vol. 83, Oxford-London-Edinburgh-New York-Paris-Frankfurt: Pergamon Press, pp. XII+255, MR 0185399, Zbl 0129.07701. A masterpiece in the multidimensional theory of singular integrals and singular integral equations summarizing all the results from the beginning to the year of publication, and also sketching the history of the subject.
