| 描述 | This book proves that Feynman‘s original definition of the path integral actually converges to the fundamental solution of the Schr?dinger equation at least in the short term if the potential is differentiable sufficiently many times and its derivatives of order equal to or higher than two are bounded. The semi-classical asymptotic formula up to the second term of the fundamental solution is also proved by a method different from that of Birkhoff. A bound of the remainder term is also proved..The Feynman path integral is a method of quantization using the Lagrangian function, whereas Schr?dinger‘s quantization uses the Hamiltonian function. These two methods are believed to be equivalent. But equivalence is not fully proved mathematically, because, compared with Schr?dinger‘s method, there is still much to be done concerning rigorous mathematical treatment of Feynman‘s method. Feynman himself defined a path integral as the limit of a sequence of integrals over finite-dimensional spaces which is obtained by dividing the time interval into small pieces. This method is called the time slicing approximation method or the time slicing method..This book consists of two parts. Part I is t |
