  skos:definition """In mathematics, a <b>principal homogeneous space</b>, or <b>torsor</b>, for a group <i>G</i> is a homogeneous space <i>X</i> for <i>G</i> in which the stabilizer subgroup of every point is trivial. Equivalently, a principal homogeneous space for a group <i>G</i> is a non-empty set <i>X</i> on which <i>G</i> acts freely and transitively (meaning that, for any <i>x</i>, <i>y</i> in <i>X</i>, there exists a unique <i>g</i> in <i>G</i> such that <span class="nowrap"><i>x</i>·<i>g</i> = <i>y</i></span>, where · denotes the (right) action of <i>G</i> on <i>X</i>).
