Contact manifolds of Pfaff dimension 3 and Symplectic manifolds of Pfaff dimension 4 have complex vectorial components as eigendirection fields of the 2-form dA with zero quadratic form. They are Spinors, not classic vectors, and are the basis of topological fluctuations, dissipation, and irreversible processes
