WebThus this is indeed a group action of G = (R,+) on C. Recall, that in polar coordinates when two complex numbers are multiplies, their ... Show that the stabilizer S(x) is a subgroup of G. Solution. Note that by definition of a group action e·x = x, so that e ∈ S(x). Let g,h ∈ S(x), that is g ·x = x and h·x = x. WebDefinition 6.1.2: The Stabilizer. The stabilizer of is the set , the set of elements of which leave unchanged under the action. For example, the stabilizer of the coin with heads (or tails) up is , the set of permutations with positive sign.
