WebOne has Hodge symmetry: complex conjugation interchanges H p, q and H q, p, and this implies that they have the same dimension. The Hodge decomposition and Hodge symmery together imply, for example, that if n is odd then the dimension of H n ( X, C) is even. This is a major topological constraint on the topology of complex projective varieties. Web20. With suitable boundary conditions, the decomposition is unique. Without them, it's not. Suppose that ( ϕ, G) and ( ϕ ′, G ′) are two different decompositions for the same function. Then. ∇ ( ϕ − ϕ ′) + ∇ × ( G − G ′) = 0. Take the divergence of both sides to find that. ∇ 2 ( ϕ − ϕ ′) = 0. So for any two distinct ...
