В 1957 г. Т. Сколем показал, чтоесли числа 1, 1/𝛼, 1/𝛽 линейно независимы над полем рациональных чисел, то последовательности [𝛼𝑛] и [𝛽𝑛] имеют бесконечно много общих членов. Т. Банг усилил этот результат:пусть 𝑆𝛼,𝛽(𝑁) — количество натуральных чисел 𝑘, 1 &lt;= 𝑘 &lt;= 𝑁, принадлежащих одновременно двум последовательностям Битти [𝛼𝑛] и [𝛽𝑚] и числа 1, 1/𝛼, 1/𝛽 линейно независимынад полем рациональных чисел, тогда 𝑆𝛼,𝛽(𝑁) ∼ 𝑁𝛼𝛽 при 𝑁 → ∞.В работе доказывается уточнение этого результата для случая алгебраических чисел.Пусть 𝛼, 𝛽 &gt; 1 — такие иррациональные алгебраические числа, что 1, 1/𝛼, 1/𝛽 линейно независимы над полем рациональных чисел. Тогда для любого 𝜀 &gt; 0 справедлива асимптотическая формула 𝑆𝛼,𝛽(𝑁) = 𝑁/𝛼𝛽 + 𝑂(︀𝑁^((1/2)+𝜀))︀.</p></abstract><trans-abstract xml:lang="en"><p>Homogeneous Beatty sequences are sequences of the form 𝑎𝑛 = [𝛼𝑛], where 𝛼 is a positive irrational number. In 1957 T. Skolem showed that if the numbers 1, 1/𝛼, 1/𝛽 are linearly independent over the field of rational numbers, then the sequences [𝛼𝑛] and [𝛽𝑛] have infinitely many elements in common. T. Bang strengthened this result: denote 𝑆𝛼,𝛽(𝑁) the number of natural numbers 𝑘, 1 &lt;= 𝑘 &lt;= 𝑁, that belong to both Beatty sequences [𝛼𝑛], [𝛽𝑚], and the numbers 1, 1/𝛼, 1/𝛽 arelinearly independent over the field of rational numbers, then 𝑆𝛼,𝛽(𝑁) ∼ 𝑁 𝛼𝛽 for 𝑁 → ∞.In this paper, we prove a refinement of this result for the case of algebraic numbers. Let 𝛼, 𝛽 &gt; 1 be irrational algebraic numbers such that 1, 1/𝛼, 1/𝛽 are linearly independent over the field of rational numbers. Then for any 𝜀 &gt; 0 the following asymptotic formula holds:𝑆𝛼,𝛽(𝑁) = 𝑁/𝛼𝛽 + 𝑂(︀𝑁^((1/2)+𝜀))︀, 𝑁 → ∞.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>однородная последовательность Битти</kwd><kwd>тригонометрические суммы</kwd><kwd>асимптотическая формула.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>homogeneous Beatty sequence</kwd><kwd>exponential sums</kwd><kwd>asymptotic formula.</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Beatty S.
