WebThe notation v 1 ∧ ⋯ ∧ v i should be understood to refer to the parallelotope made from the vectors v 1, ⋯, v i ∈ V. If i < d = dim V then the "volume" of the parallelotope v 1 ∧ ⋯ ∧ v i is always zero; keep in mind the key point that the Grassmann algebra on V is a priori concerned with d -dimensional volume. In mathematics, the Grassmannian Gr(k, V) is a space that parameterizes all k-dimensional linear subspaces of the n-dimensional vector space V. For example, the Grassmannian Gr(1, V) is the space of lines through the origin in V, so it is the same as the projective space of one dimension lower than V.

Now, as advertized, we use the fact that η integrates to 0 over the closed submanifold S: ∫Sη = 0, so ∑ η(si) = Oη(ϵ). Since ϵ > 0 was arbitrary, we have ∑ η(si) = 0.
