Chow CoordinatesA generalization of Grassmann Coordinates to -D varieties of degree in , where is an -Dprojective space. To define the Chow coordinates, take the intersection of a -D Variety of degree by an -D Subspace of . Then the coordinates of the points of intersectionare algebraic functions of the Grassmann Coordinates of , and by taking a symmetric function of the algebraicfunctions, a hHomogeneous Polynomial known as the Chow form of is obtained. The Chow coordinates are then theCoefficients of the Chow form. Chow coordinates can generate the smallest field of definition of a divisor. References
