WebSOLUTION: Maximal ideals in a quotient ring R/I come from maximal ideals Jsuch that I⊂ J⊂ R. In particular (x,x2 +y2 +1) = (x,y2 +1) is one such maximal ideal. There are multiple ways to see this ideal is maximal. One way is to note that any P∈ R[x,y] not in this ideal is equivalent to ay+ bfor some a,b∈ R.

WebAug 22, 2024 · The ideal ( x, z) is the prime ideal you spotted; it's not maximal, but any prime strictly containing it is. If z ∈ P then P ⊇ ( z, x z, x 2 y 2 − z 3) = ( x 2 y 2, z). As P is prime and x 2 y 2 ∈ P then either x ∈ P or y ∈ P. The x ∈ P case is dealt with, the y ∈ P case gives P ⊇ ( y, z) and the only such P that isn't maximal is ( y, z).
