计数乘法近似

Counting multiplicative approximations

Sam Chow, Niclas Technau

摘要:

Littlewood的一个著名猜想(c。1930)涉及用相同分母的有理数近似两个实数,乘以误差。在一篇不太知名的论文中,Wang和Yu(1981)建立了一个近似数的渐近公式,几乎总是有效的。使用定量Koukoulopoulos-Maynard定理Aistleitner-Borda-豪克,连同边界所产生的理论玻尔集,我们推导出预期的数量级的下界为非均匀和纤维细化的问题。

英文摘要:

A famous conjecture of Littlewood (c. 1930) concerns approximating two real numbers by rationals of the same denominator, multiplying the errors. In a lesser-known paper, Wang and Yu (1981) established an asymptotic formula for the number of such approximations, valid almost always. Using the quantitative Koukoulopoulos--Maynard theorem of Aistleitner--Borda--Hauke, together with bounds arising from the theory of Bohr sets, we deduce lower bounds of the expected order of magnitude for inhomogeneous and fibre refinements of the problem.
