Resolution of the symmetric algebra of an (n+1)-generated ideal of depth n

  • Rémi Bignalet-Cazalet

摘要

We provide a free resolution of the symmetric algebra of the ideal of an \((n+1)\) ( n + 1 ) -generated ideal of depth n over a Noetherian ring. The resolution is given in terms of the resolution of the ideal itself and of a Buchsbaum-Rim complex associated to an explicit map.
