Ч. Титчмарша применяется к доказательству локальной теоремы Кронекера. Для произвольной конечной последовательности ¯𝜆 = (𝜆1, . . . , 𝜆𝑟) вещественных чисел, линейно независимых над полем Q, и для любого 𝜀 &gt; 0 этот метод даёт явную верхнюю оценку величины ℎ = ℎ(𝜀,¯𝜆) такой, что для всякой последовательности ¯𝛼 = (𝛼1, . . . , 𝛼𝑟) любой интервал длины ℎ содержит точку 𝑡 такую, что ‖𝑡𝜆𝑠 − 𝛼𝑠‖ &lt;= 𝜀, 1 &lt;= 𝑠 &lt;= 𝑟. Эта оценка уступает по точности наилучшей известной на сегодняшний день, однако проста в выводе и в приложениях приводит, по сути, к результатам той же точности, что и наилучшая.Во второй части помещены воспоминания авторов об академике Алексее Николаевиче Паршине.</p></abstract><trans-abstract xml:lang="en"><p>In the first part of the paper, a modification of elementary Titchmarsh’s method is applied to the proof of the local Kronecker’s theorem. For any finite real sequence ¯𝜆= (𝜆1, . . . , 𝜆𝑟) of linearly independent (over Q) numbers and for any 𝜀 &gt; 0, this method leads to the explicit upper bound of the value ℎ = ℎ(𝜀,¯𝜆) with the following property: for any real sequence ¯𝛼 = (𝛼1, . . . , 𝛼𝑟), any interval of the length ℎ contains a point 𝑡 such that ‖𝑡𝜆𝑠 − 𝛼𝑠‖ &lt;= 𝜀, 1 &lt;= 𝑠 &lt;= 𝑟. Such estimate is weaker than the best known, but it’s proof is quite simple and leadsto the same (in essence) results in the applications.The second part contains the short memoirs concerning the academician Alexey NikolaevichParshin who passed away on June, 18 this year.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>локальная теорема Кронекера</kwd><kwd>совместные приближения</kwd><kwd>логарифмы простых чисел</kwd><kwd>бесквадратные числа.</kwd></kwd-group><kwd-group xml:lang="en"><kwd>local Kronecker’s theorem</kwd><kwd>simultaneous approximations</kwd><kwd>logarithms of primes</kwd><kwd>squarefree numbers.</kwd></kwd-group><funding-group><funding-statement xml:lang="ru">Исследование первого автора выполнено за счет гранта Российского научного фонда (проект № 19-11- 00001) в Математическом институте им.
