On the Distribution of Integral Well-rounded Lattices in Dimension Two, Part II
A lattice is called well-rounded if its minimal vectors span the corresponding Eucildean space. We continue studying the distribution of well-rounded full-rank sublattices of Z^2 by examining the growth of the number of such lattices with fixed determinant. We also introduce a zeta-function associated with this class of lattices and study some of its properties. By comparing its behaviour to that of two well-known zeta functions we obtain some additional information. This is continuation of the talk I gave on September 27, 2006, however I will review all the previously discussed results and background to make this talk entirely self-contained.
