Equivalence between path integral formulation and matrix formulation

  1. Apr 17, 2005 #1
    Does anyone know where to find the "direct" (not by prove they are both equal to Schrodinger formualtion )proof?

    There's no direct proof.Both matrix mechanics and Schrödinger's wave mechanics are particular representations of Dirac's abstract formulation.So the equivalence is between formulations:path integral (R.P.Feynman) and traditional (vectors and operators,P.A.M.Dirac).

    There's a famous book which deals with this issue:

    Feynman and Hibbs,"Quantum Mechanics and Path Integrals",McGraw & Hill,1965.

    The essential of that book is found as a chapter/subchapter in many QM texts,outta which i'd like to mention Sakurai and Cohen-Tannoudji.
