Orders in quadratic fields. II
This work continues part I with the same title [ibid., No. 3, 45-48 (1993; Zbl 0795.11056)] and also complements the work of the authors where they dealt with the real case [Reduced ideals, the divisor function, continued fractions and class numbers of real quadratic fields, to appear in Publ. Math.]. Namely, they provide a sharp lower bound for the class number of any complex quadratic order, which is a generalization of the Rabinowitsch result for the class number one problem. [For part III, see the paper reviewed below].
