P 2 in short intervals
Annales de l'Institut Fourier, Tome 31 (1981) no. 4, pp. 37-56.

On démontre que l’intervalle [x,x+x 0,45 ] contient un entier ayant au plus deux facteurs premiers dès que x est un nombre réel suffisamment grand.

For any sufficiently large real number x, the interval [x,x+x 0,45 ] contains at least one integer having at most two prime factors .
