• author with Henri Cohen in 1979 of the program called Isabelle, a high-level arithmetic-oriented interpreter ancestor of PARI/gp

• (with J.-M.Deshouillers and G. Tenenbaum) Laws of distribution of divisors, 1, Acta Arithmetica, t. 34, 1979, p. 7-19 the distribution of the logarithms of the integer divisors follows on average an Arcsine law.

• (with J.-M. Deshouillers and R. Balasubramanian) Waring problem for bisquares. 1: solution diagram, C-R Acad. Sci., Paris, 303, Ser. I, 1986, p. 85-88; 2: auxiliary results for the asymptotic theorem, C-R Acad. Sci., Paris, 303, Ser. I, 1986, p. 161-163 g(4) = 19: for Waring's problem in the case of bisquares, the smallest number of bisquares necessary to express a natural number as a sum of bisquares is equal to 19.

• several articles with H. Cohen and with M. El Marraki (1993 to 2007) explicit upper bounds of the summatory functions of the Möbius function.

• Discrepancy of Farey sequences, Bordeaux Journal of Number Theory, Volume 11, No. 2, 1999, p. 345-367 the absolute discrepancy of the Farey sequence of order n is exactly 1/n.

• (with B. Landreau) Polynomials of degree greater than 2 taking many prime values, https://arxiv.org/pdf/1402.7312.pdf (2014) polynomials producing n prime numbers for n consecutive values of x, the absolute record is n = 58 found in 2010 for P(x) = (1/72) x^6 – (5/24) x^5 – (1493/72 ) x^4 + (1027/8) x^3 + (100471/18) x^2 – (11971/6) x – 57347, from x = –42 to x = 15
