ABSTRACT
The transition amplitudes 4.47 and 4.82 of chapter 4 may be generalized for a problem with s degrees of freedom that may be described by a set of operators q ̂ = q ̂ α α = 1 s , p ̂ = p ̂ α α = 1 s https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003145554/e05d5bc2-9f6b-44fc-95c4-8a9db92e5483/content/eqni6_1.jpg"/> : Κ q ″ , t ″ ; q ′ , t ′ = ∫ ∏ α = 1 s D p α D q α exp i ℏ ∫ t ′ t ″ ∑ α = 1 s p α q . α − Η p q d t https://s3-euw1-ap-pe-df-pch-content-public-p.s3.eu-west-1.amazonaws.com/9781003145554/e05d5bc2-9f6b-44fc-95c4-8a9db92e5483/content/eqn6_1.jpg"/>
