The k-dimensional Duffin and Schaeffer conjecture
Journal de théorie des nombres de Bordeaux, Tome 1 (1989) no. 1, p. 81-88
Nous montrons que la conjecture de Duffin et Schaeffer est vraie en toute dimension supérieure à 1.
We show that the Duffin and Schaeffer conjecture holds in all dimensions greater than one.
