A modification of the Ford geometric approach to the problem of approximation of complex numbers by elements of an imaginary quadratic number field is developed. An upper bound for the Hurwitz constant for the field is obtained in terms of the geometry of the isometric fundamental domain for the cor

โฆ Synopsis
A new approach to inhomogeneous Diophantine approximation is given and a method for the computation of inhomogeneous minima of binary quadratic forms is derived. The new method is simpler than earlier ones of Barnes and SwinnertonDyer. As an application, a new proof of a theorem of Davenport, which gives the complete sequence of inhomogeneous minima for the form (x^{2}-x y-y^{2}), is given. C) 1994 Academic Press, Inc.
