The Schrödinger equation contains one complex valued dependent variable, [tex]\Psi[/tex], which depends on the time coordinate t and 3N space coordinates, where N is the number of particles. It also contains a set of real valued parameters [tex]m_a[/tex] with a ranging from 1 to N, indicating the mass of each particle in the system, and a real valued parameter V, the system's potential energy, which depends on the same time and space coordinates.
