A mathematical approach to Wick rotations

, 2020
In this thesis we define Wick-rotations mathematically using pseudo-Riemannian geometry, and relate Wick-rotations to real geometric invariant theory (GIT). We discover some new results concerning the existence of Wick rotations (of various signatures).

Rotaciones y cuaterniones (sin secretos) (Rotations and quaternions: The easy and convenient way)

Revista Digital Matemática, Educación e Internet
Hay mucha literatura dispersa sobre cuaterniones y rotaciones que está orientada a aplicaciones prácticas pero no tanto a desarrollar la intuición y las matemáticas que hay detrás de las fórmulas.
