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