A class of entanglement monotones for general pure multipartite states   based on complex projective variety
  We construct a measure of entanglement for general pure multipartite states based on Segre variety. We also construct a class of entanglement monotones based on the Pl\"{u}cker coordinate equations of the Grassmann variety. Moreover, we discuss and compare these measures of entanglement.
