http://www.rvirk.com/notes/student/orbitstabilizer.pdf WebA stabilizer is a part of a monoid (or group) acting on a set. Specifically, let be a monoid operating on a set , and let be a subset of . The stabilizer of , sometimes denoted , is the set of elements of of for which ; the strict stabilizer' is the set of for which . In other words, the stabilizer of is the transporter of to itself.
WebSo now I have to show that $(\bigcap_{n=1}^\infty V_n)\cap\bigcap_{q\in\mathbb Q}(\mathbb R\setminus\{q\})$ is dense, but that's a countable intersection of dense open subsets of $\mathbb R$, so by the Baire category theorem . . . The Baire category theorem gives sufficient conditions for a topological space to be a Baire space. WebApr 18, 2024 · The orbit of $y$ and its stabilizer subgroup follow the orbit stabilizer theorem as multiplying their order we get $12$ which is the order of the group $G$. But using $x$ we get $2\times 3 = 6$ instead of $12$. What am I missing? group-theory group-actions group-presentation combinatorial-group-theory Share Cite Follow edited Apr 18, 2024 at 12:08
