Find all homomorphisms from z to z6
WebThe kernel of a homomorphism must be a normal subgroup of the inverse image. Simply S 3 has 3 normal subgroups which are { e }, A 3, and S 3. Let ϕ: S 3 → Z 6. Then possible kernels are { e }, A 3, and S 3. Firstly, try { e }. By First Isomorphism Theorem, S 3 / e which is S 3 itself, S 3 ≃ ϕ ( S 3). WebDec 13, 2016 · 1 Answer Sorted by: 5 Counting homomorphisms and counting normal subgroups are not the same thing, so no, this method does not work. Instead, let a, b ∈ G = Z / 2 × Z / 2 be generators of the two factors, so: a, b commute with each other; a, b are each of order 2, so they generate subgruops a , b which are cyclic of order 2;

(Remember that to specify a group homomorphism ˚: Z m!Z Web2 Answers Sorted by: 21 A ring homomorphism f: Z m → Z n is uniquely determined by the conditions: m f ( 1) = 0 and f ( 1) 2 = f ( 1). In order to find out how many ring homomorphisms there are we have to count the number of elements of the set { e ∈ Z n: e 2 = e, m e = 0 }.
Web15.20 Homomorphisms from Z 6 Z6: As in Q15, Z6 is a partition of Z modulo 6. Therefore the elements of Z 6 are equivalent to their equivalency classes. Furthermore, note that a homomorphism from Z 6 Z6 is fully defined by the image of 1 because all elements of Z 6 are obtainable from 1. Therefore, a homomorphism from Web(a) Find all homomorphisms from Z12, the cyclic group of order 12, to Z6. For each homomorphism f : Z12 −→ Z6, determine the kernel ker(f) and the image f(Z12). By determine, I mean list all the elements in the kernel and in the image. (b) Which of the homomorphisms (if any) you found in part (a) are ring homomorphisms?
