Find all group homomorphisms φ : z → s3
Web3 Answers Sorted by: 20 Note that a homomorphism from S 3 to Z 6 is a homomorphism into an abelian group. Therefore, there is a bijection h o m ( S 3, Z 6) ≃ h o m ( S 3 / [ S … WebLagrange's Theorem: In any finite group, the order of a subgroup must divide the order of the group. (The converse is not true!) The two together imply that $ a $, the image of $\varphi (1_ {Z_n})$, must divide not only $n$ (by Lagrange's Theorem) but …

Web9.Find all possible actions on the group Z=2Z on Z=3Z. Solution: Since a group action of Z=2Z on Z=3Z = f0,1,2gis the same as a group homomorphism Z=2Z !Perm(f0,1,2g), and Perm(0,1,2g) ˘=S 3, then we are looking for all possible homomorphisms from Z=2Z to S 3. As 0 2Z=2Z must get mapped to e 2S 3, we need only say what happens to 1 2Z=2Z. WebMay 2, 2024 · It has an identity element $e$ and a non-identity element $a$ such that $a^2=e$. A homomorphism $f_1:C_2 \to C^*$ is determined by the value of $f(a)$. Since …

WebLet's look at group homomorphisms first. If f: Z / 6 Z → Z / 15 Z is given, then it is determined by f ( 1 + 6 Z) = a + 15 Z and it must be. 6 ( a + 15 Z) = 0 + 15 Z. that is, 6 a … http://fmwww.bc.edu/gross/MT310/hw06ans.pdf
WebThe general way to find all homomorphism Z n → G for an arbitray abelian group G is the following: Suppose ϕ: Z n → G is a group homomorphism, as you said, it is determined by the image of 1, so the question really is which choices of g ∈ G give a homomorphism Z n → G when picked as the image of 1?
WebDetermine all homomorphisms from Z to S 3. Let ˚: Z !S 3 be a homomorphism. ˚(Z) is an Abelian group, so ˚(Z) 6= S 3. So there is no surjective homomorphism.
