I don't know how to find all zero divisors for polynomials in several variables. For example:

$\mathbb{Z}_2[X,Y]/(X^2,XY,Y^2)\quad $ or $\quad \mathbb{Z}_4[X,Y]/(X^2,Y^2-XY)$

Can we to proceed like in $\mathbb{Z}_2[X]$ over a non irreducible polynomial by using euclidian divison, and find all zero divisors for this ring?

  • $\begingroup$ $=0$ but I want a method or a procedure that I must use to find all of the zero divisor $\endgroup$ – Mary Maths Apr 21 at 12:48

  • $\begingroup$ I am not a native speaker that why I didn't express my self well. I change it now. My goal is to find all zero divisor not only one $\endgroup$ – Mary Maths Apr 21 at 13:10

    $\begingroup$ Both rings are local and artinian, so the maximal ideal is the set of all zero-divisors. $\endgroup$ – user26857 Apr 21 at 22:41
