WebFeynman realized that due to the fundamental composition law of the time evo-lution operator (see Section 1.7), the amplitude (2.1) could be sliced into a large number, say N+1, of time evolution operators, each acting across an infinitesimal time slice of thickness ǫ≡ tn −tn−1= (tb − ta)/(N+1)>0: Webtion of the Feynman kernel (we use the notions semiclassical and WKB simultaneously) is based on the fact that the harmonic oscillator, respectively, the general quadratic …

http://guidetothecosmos.com/feynman/FS1A_Answers.pdf WebA homework problem on the 1-dim Dirac equation occurring in Feynman and Hibbs’ “Quantum Mechanics and Path Integrals”,[10], (before even the path integral of a free non-relativistic particle has been written down!): 69 “Suppose a particle moving in one dimen-sion can go only forward or backward at the velocity of light. For convenience, we WebIn order not to deal with purely oscillatory integrands, Feynman uses a prescription Δ t M Δ t M − i 0 + where an infinitesimal negative imaginary part is added to make the integrand exponentially decaying. In other words, under a Wick rotation Δ t E ≡ i Δ t M to Euclidean time, Δ t E should have a positive real part. rudolf backof
