The adjunction formula is false when the conormal exact sequence is not a short exact sequence. However, it is possible to use this failure to relate the singularities of X with the singularities of D. Theorems of this type are called inversion of adjunction. They are an important tool in modern birational geometry.
We give a short report on the adjunction formula for line bundles as it can be found in Griffiths-Harris “Principles of Algebraic Geometry". Theorem 1. Let X be a

Typically any formula for computing the canonical divisor comes with a fancy name: Theorem 2.8 (Adjunction formula). Let X be a smooth variety and let S be a smooth divisor. Then (KX + S)|
12 Apr 2008 In algebraic geometry, the adjunction formula states that if are smooth algebraic varieties, and is of codimension 1, then there is a natural
25 Oct 2013 As written the claimed formula seems to be incorrect. To see this take D="0": then the formula would say that ??|C=?C. But that contradicts what
13 Jul 2012 To answer this question, we will need a relative version of the adjunction formula. Recall from an earlier installment that in a closed symplectic
