MultiGradedRationalMap :: Hm1Rees0Strategy

Hm1Rees0Strategy -- A strategy for degreeOfMap


When this strategy is used then the degree of the map is computed directly from the multiplicity of $[H_m^1(Rees(I))]_0$. It contains an implementation of Corollary 2.12 in Degree and birationality of multi-graded rational maps.

For the programmer

The object Hm1Rees0Strategy is a symbol.
