The full-twist braid commutes with any element of the braid group
Коса полный оборот коммутирует с произвольным элементом группы кос
Summary
[edit]DescriptionThe full-twist braid is central.svg |
English: The picture proves that the full-twist braid is a central element of the braid group. In other words, it commutes with any braid (shown as a rectangle). The right braid is obtained from the left one by moving the rectangle through the strands via twisting it twice.
Русский: Изображение доказывает, что полный оборот является центральным элементом группы кос. Иными словами, он коммутирует с произвольной косой (показана в виде прямоугольника). Правая коса получается из левой протаскиванием прямоугольника через нити путём проворачивания его дважды. |
