How To Find Maximal Ideals

How To Find Maximal Ideals. 1) Find all prime ideals and all maximal ideals of [TEX] \mathbb{Z}_{12}[/TEX] 2) Find all prime ideals and maximal ideals of \(\displaystyle \mathbb{Z}_2 \ \times \ \mathbb{Z}_4\) Last edited by a moderator Feb 10 2013.

PDF fileWe are now ready to prove the main result an ideal I in Z n is maximal if and only if I = hpi where p is a prime dividing n If I has this form and J is another ideal in Z n with I ⊂ J then J = hdi for some d dividing n By our comments above this means that d divides p ie d = 1 or d = p which means that J = Z n or J = I proving that I is maximal For.

Comm. Algebra Maximal Ideals

Conversely for any b ∈ I let w ( b) ≥ k and write b = p w u ′ = p k p w − k u ′ ∈ p k Z p This shows that I ⊆ p k Z p Z p is a local ring its maximal ideal is p Z p Unless you meant Z / n Z and not the ring of p adic numbers Share Follow this answer to receive notifications answered Sep 5.

Okay when I draw out the ideal lattice for these it’s obvious to see which ideals are maximal For part a b and c a) For Z 8 is maximal b) For Z 10 and are maximal c) For Z 12 and are maximal d) Requires a proof Lattice fails20190413201705052011120920060829.

Maximal ideal Wikipedia

An ideal (left right or 2sided) M in a ring R is said to be maximal if it is proper ie not equal to the whole ring R and there no such ideal I lying strictly between M and R Accordingly {0} is a maximal ideal if R has no ideals other than R and {0} Hence if R is any division ring or a field then {0} will be a maximal ideal.
