First, we use the theory of characteristics of first order partialdifferential equations to derive the guiding equation directly from the QuantumEvolution Equation (QEE). After obtaining the general result, we apply it to aset of evolution equations (Schroedinger, Pauli, Klein-Gordon, Dirac) to showhow the guiding equation is, actually, the characteristic velocity of thecorresponding matter field equations.

Applications of the Characteristic Theory to the Madelung-de  Broglie-Bohm System of Partial Differential Equations: The Guiding Equation  as the Characteristic Velocity
