According to Bader, a critical point of the electron density is characterized by its (ω,σ) pair of values, ω and σ being the rank and the signature, respectively. The rank is the number of non-zero curvatures of the electron density at the critical point and the signature is the algebraic sum of the signs of these eigenvalues.
