In mathematics, a principal homogeneous space, or torsor, for a group "G" is a homogeneous space "X" for "G" such this.
The stabilizer subgroup of any point is trivial. A principal homogeneous space is a homogeneous space "X" for "G" such this. This was in mathematics. Torsor, for a group "G" is a homogeneous space "X" for "G" such this. This was in mathematics.
