A time-dependent variant of the WKB method is developed for propagators which do not have the simple Feynman structure K = jexp(iS/h) with j = j( t). The method is applied to radial propagators for N-dimensional isotropic oscillators. An expansion in ascending powers of h results in an asymptotic se
This paper extends the research of Wiegel (J. Math. Phys. 21 (1980) 2111) on random walks which differ from free random walks through the occurrence of an extra weightfactor ( 1) at every crossing of a half-line. Starting from a new closed-form expression for the weight distribution of these walks,
