Webnote is to present proofs of Cauchy’s theorem and Sylow’s theorems based almost entirely on the application of group actions and the class equation (a.k.a. the orbit-stabilizer theorem). These proofs demonstrate the exibility and utility of group actions in general. As we will see, the simplicity of the class equation, WebJan 10, 2024 · Orbit Stabilizer Theorem Proof. We define a mapping φ: G → G⋅a by. φ (g) = g⋅a ∀ g∈G. Now for g, h ∈ G, we have. φ (g) = φ (h) ⇔ g⋅a = h⋅a ⇔ g -1 h⋅a=a ⇔ g -1 h∈G … Webtheory in its formulation, it is remarkable thatno proof has ever been found that doesn’t use representation theory!
