groups and physics coadjoint action momentum

En résumé (grâce à un LLM libre auto-hébergé)

  • The text explains the basics of groups in physics, focusing on square matrices and their properties.
  • It describes the group axioms, particularly the existence of an identity element and the internal composition law.
  • A simple example of a group is provided using one-parameter matrices, illustrating how they can form a group.

...Everything that follows in this domain will revolve around groups. Can we provide a simplified overview of this part without delivering a complete course on groups? Moreover, what is the relationship between groups and particles? All of this seems quite mysterious to a beginner.

...First, what is a group? In what follows, we consider simply
