Research Abstract |
We studied Stanly-Reisner ideals, which are squarefree monomial ideals in polynomial rings. As a result we have proved that any powers areCohen-Macaulay if a certain m-th power of a Stanley-Reisner ideal is Cohen-Macaulay, where m is more than two. In this case the original ideal is a complete intersection. This is a refinement of the Cowsik-Nori theorem in the case of monomial ideals.
