The Quantum Wave Packet and the Feynman De Broglie Bohm Propagator of   the Linearized Sussmann Hasse Albrecht Kostin Nassar Equation along a   Classical Trajetory
  In this paper we study the quantum wave packet and the Feynman-de Broglie_Bohm propagator of the linearized Sussmann_Hasse_Albrecht_Kostin_Nassar equation along a classical trajetory
