A generalization of Grassmann coordinates to -D
algebraic varieties of degree
in
, where
is an
-dimensional projective space. To define the Chow coordinates,
take the intersection of an
-D algebraic variety
of degree
by an
-D subspace
of
. Then the coordinates of the
points of intersection are algebraic functions of the Grassmann
coordinates of
,
and by taking a symmetric function of the algebraic functions, a homogeneous
polynomial known as the Chow form of
is obtained. The Chow coordinates are then the coefficients
of the Chow form. Chow coordinates can generate the smallest field of definition
of a divisor.
