Submodules of the Deficiency Module

  • Juan C. Migliore
Part of the Progress in Mathematics book series (PM, volume 165)


In this chapter we will define certain submodules of the first deficiency module of a closed subscheme Z of ℙ n , and see how they give a more refined measure of the failure of the ideal of Z to have certain nice properties. We then describe some applications of these submodules from the literature.
