Domain-specific

• Ideal sheaf
  • An ideal sheaf on a ringed space \((X,\mathcal O_X)\) is a subsheaf \(\mathcal I\) of \(\mathcal O_X\) such that \(\mathcal I(U)\) is an ideal of \(\mathcal O_X(U)\) for every open \(U\); on a scheme, quasi-coherent ideal sheaves correspond to closed subschemes through \(\mathcal O_X/\mathcal I\).
