 rt\, Austria_\n\nGiven a square matrix B' over a (commutative) ring S\, th
 e null ideal\nN_0(B') is the ideal consisting of all polynomials f in S[X]
  for which\nf(B')=0. In the case that S=R/J is the residue class ring of a
  ring R\nmodulo an ideal J\, we can equivalently study the so-called J-ide
 als\n\nN_J(B) =  { f in  R[X]  |  f(B) in M_n(J) }
