Abstract: This work consists of two main parts.
In the first part, which presents the introduction, given a fairly comprehensive overview of the theory of the hyperbolic Zeta-function of lattices. Unlike earlier reviews is that, firstly, most of the results of the General theory particularized to two-dimensional case. This is done because the main goal of this lattice is quadratic fields. And these lattices are two-dimensional.
Secondly, the first explicit form of the functional equation for hyperbolic Zeta-function of one and two diagonal lattices.
In the second part we investigate the behavior of the hyperbolic Zeta-function of the lattice $\Lambda(t)$ of the quadratic field when the growth parameter $t$. For applications of the theory of hyperbolic Zeta-function lattices to estimate the error of the approximate integration on the class of $E_s^\alpha$ by using generalized parallelepipedal nets with weights it is important to have assessment through growing the determinant of the lattice.
In this work, we derived a new asymptotic formula for the hyperbolic Zeta function lattices of quadratic fields. The peculiarity of this formula is that it has a main two-term member and remaining a member with the assessment of incoming constants. In this formula more specific correlation between the hyperbolic Zeta function of lattices of quadratic fields and quadratic field characteristics as: the Zeta function of the Dedekind principal ideals of a quadratic field, the derivative of the Zeta-function of Dedekind principal ideals of a quadratic field, quadratic field by the regulator and the fundamental unit of the quadratic field.
