非线性区域长方体特征方程根的渐近估计
Asymptotic estimates for roots of the cuboid characteristic equation in the nonlinear region
摘要：
完美的长方体是长方体。它的边、面对角线和空间对角线的长度都是整数。到目前为止，还没有一个这样的长方体是已知的，尽管描述它们的丢番图方程很容易写出。长方体的特征方程是由长方体的初始方程导出的一个12次丢番图方程，并与它们等价。在第二个长方体猜想的情况下，它简化为一个十次方程。该方程包括两个参数。以前的各种渐近根这个方程进行了研究，因为它的参数趋于无穷大，无论是单独或同时提供一些线性组合，他们是保持有限的。本文将这种线性组合用某种非线性表达式代替。
英文摘要：
A perfect cuboid is a rectangular parallelepiped. Its edges, its face diagonals, and its space diagonal are of integer lengths. None of such cuboids is known thus far, though the system of Diophantine equations describing them is easily written. The cuboid characteristic equation is a twelfth degree Diophantine equation derived from the initial cuboid equations and equivalent to them. In the case of the second cuboid conjecture it reduces to a tenth degree equation. This equation comprises two parameters. Previously various asymptotics for roots of this equation were studied as its parameters tend to infinity either separately or simultaneously provided some linear combination of them is preserved finite. In the present paper this linear combination is replaced by a certain nonlinear expression.
