О. Гельфонд доказал, что при условии взаимной простоты 𝑏 − 1 и 𝑑 суммы цифр разложений натуральных чисел в 𝑏-ичную систему счисления равномерно распределены по арифметическим прогрессиям с разностью 𝑑. Также он получил степенную оценку остаточного члена в данной задаче.Мы рассматриваем аналог задачи Гельфонда для представлений Цекендорфа натуральных чисел в виде суммы чисел Фибоначчи. Показано, что в данном случае также имеет место равномерная распределенность сумм цифр по арифметическим прогрессиям. Более того, в случае, когда разность арифметической прогрессии 𝑑 равняется 2, ранее было доказано, что остаточный член задачи является логарифмическим. В настоящей работепоказано, что при 𝑑 ≥ 3 остаточный член задачи является степенным и найдена неулучшаемая по порядку оценка для него.В основе доказательства лежит детальное изучение остаточного члена в точках, равных числам Фибоначчи. Показано, что остаточный член в произвольной точке может быть оценен через значения остаточного члена в числах Фибоначчи. Для последних удается получить линейное рекуррентное соотношение с постоянными коэффициентами, и, более того, точную формулу в терминах некоторых определителей Вандермонда, связанных с корнями характеристического многочлена.Кроме того, достаточно неожиданно линейное рекуррентное соотношение для остаточного члена в точках, равных числам Фибоначчи, оказывается связанным с некоторыми комбинаторными треугольниками, аналогичными треугольнику Паскаля.</p></abstract><trans-abstract xml:lang="en"><p>A.O. Gelfond proved that if 𝑏−1 and 𝑑 are coprime, the sums of digits of the 𝑏-ary expressions of natural numbers are uniformly distributed over arithmetic progressions with difference 𝑑. He also obtained a power estimate for the remainder term in this problem.We consider an analogue of Gelfond’s problem for Zeckendorf representations of naturals as a sum of Fibonacci numbers. It is shown that in this case we again have the uniform distribution of the sums of digits over arithmetic progressions.Moreover, in the case when the difference of the arithmetic progression 𝑑 is equal to 2, it was previously proved that the remainder term of the problem is logarithmic. In the present paper, it is shown that for 𝑑 ≥ 3 the remainder term of the problem is a power and an unimprovable in order estimate for it is found.The proof is based on the detailed study of the remainder term at the Fibonacci numbers. It is shown that the remainder term at an arbitrary point can be estimated through the values of the remainder term in points equal to Fibonacci numbers. For them, it is possible to obtain a linear recurrence relation with constant coefficients, and, moreover, and an exact formula in terms of some Vandermonde determinants connected with the roots of the characteristicpolynomial.Moreover, quite surprisingly, the linear recurrence relation for the remainder term at the Fibonacci points turns out to be connected with some combinatorial triangles, similar to Pascal’s triangle.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>задача Гельфонда</kwd><kwd>суммы цифр</kwd><kwd>числа Фибоначчи</kwd><kwd>представление Цекендорфа</kwd><kwd>треугольник Паскаля.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>Gelfond problem</kwd><kwd>sum of digits</kwd><kwd>Fibonacci numbers</kwd><kwd>Zeckendorf representation</kwd><kwd>Pascal triangle.</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">Gelfond A.
