EquiprojectableDecomposition(lrc, R)

Parameters

lrc

-

list of regular chains of R

R

-

polynomial ring

Description

• 

The command EquiprojectableDecomposition(lrc, R) returns the equiprojectable decomposition of the variety given by lrc.

• 

The variety encoded by lrc is the union of the regular zero sets of the regular chains of lrc.

• 

It is assumed that every regular chain in lrc is zero-dimensional and strongly normalized.

• 

This command is part of the RegularChains[ChainTools] package, so it can be used in the form EquiprojectableDecomposition(..) only after executing the command with(RegularChains[ChainTools]).  However, it can always be accessed through the long form of the command by using RegularChains[ChainTools][EquiprojectableDecomposition](..).
