Frobenius distributions for real quadratic orders
Journal de théorie des nombres de Bordeaux, Tome 7 (1995) no. 1, pp. 121-132.

We present a density result for the norm of the fundamental unit in a real quadratic order that follows from an equidistribution assumption for the infinite Frobenius elements in the class groups of these orders.
