MultiGradedRationalMap :: Hm1Rees0Strategy

Hm1Rees0Strategy -- A strategy for degreeOfMap

Description

When this strategy is used then the degree of the map is computed directly from the multiplicity of [Hm1(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.
