ABSTRACT
At the beginning of the previous chapter when we looked at the evaluation map e : G → Ox , we came upon subsets of G of the form αG x, where x ∈ X, α ∈ G. Such subsets are called cosets of the stabilizer Gx in G. In general, given a subgroup K < G, we call a subset α K : = { α κ ∈ K } https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781315273167/d8d3126f-3b78-4a67-b8e1-1df8c97b50c9/content/eq696.tif"/>
