Section 2 examines the equation for a new scale, which allows consolidating two graphs of different curves (Example 4). The existence of a new equation of a fixed set of points in new coordinate systems is proved (Theorems 1, 2; Examples 1–3). Theorem 1 treats two different variables as one argument; Theorem 2 yields two equations for the complex field: a regular function and a diagonal field. Possible application to the proof of Fermat&#039;s Last Theorem is noted.</p> </abstract>    <trans-abstract xml:lang="ru"> <p>В статье рассматриваются новые системы координат на комплексной плоскости и уравнения фиксированных множеств точек (графиков). В разделе 2 исследуется уравнение для нового масштаба, позволяющее совместить два графика различных кривых (пример 4). Доказывается существование нового уравнения фиксированного множества точек в новых системах координат (теоремы 1, 2; примеры 1–3). В теореме 1 две различные переменные рассматриваются как один аргумент; в теореме 2 для комплексного поля получены два уравнения: регулярная функция и диагональное поле. Отмечается возможное применение к доказательству большой теоремы Ферма.</p> </trans-abstract>       <kwd-group xml:lang="ru">  <kwd>системы координат</kwd>  <kwd>теорема Ферма</kwd>  <kwd>комплексная плоскость</kwd>  <kwd>фиксированное множество точек</kwd>  <kwd>регулярная функция</kwd>  <kwd>диагональное поле</kwd>  <kwd>новый масштаб</kwd>  </kwd-group>    <kwd-group xml:lang="en">  <kwd>complex plane</kwd>  <kwd>coordinate systems</kwd>  <kwd>fixed set of points</kwd>  <kwd>regular function</kwd>  <kwd>diagonal field</kwd>  <kwd>new scale</kwd>  <kwd>Fermat&#039;s theorem</kwd>  </kwd-group>      </book-part-meta> </book-part> </front>  <back> <ref-list> <title>References</title>  <ref id="ref1"> <label>1</label> <citation-alternatives>   <mixed-citation xml:lang="en">Lavrentiev M.A. The methods of theory functions of complex variable / M.A. Lavrentiev, B.V.
