MultiGradedRationalMap :: SatSpecialFibStrategy

SatSpecialFibStrategy -- A strategy for degreeOfMap

Description

When this strategy is used then the degree of the map is computed directly from the multiplicity of the saturated special fiber ring of I. The degree of the rational map then can be obtained from Theorem 2.4 in Degree and birationality of multi-graded rational maps.

For the programmer

The object SatSpecialFibStrategy is a symbol.
