ar X iv : h ep - t h / 01 09 18 5 v 1 2 4 Se p 20 01 Once again : Instanton method vs . WKB
A recent renewed claim that the instanton method and the WKB method do not lead to identical results in the 1–loop approximation is repudiated. It is pointed out that the WKB method, or its equivalent, yields the instanton result provided the boundary conditions are imposed on wave functions which are properly matched in domains of overlap.

A recent analytic test of the instanton method performed by comparing the exact spectrum of the Lamé potential (derived from representations of a finite dimensional matrix expressed in terms of su(2) generators) with the results of the tight–binding and instanton approximations as well as the standard WKB approximation is commented upon. It is pointed out that in the case of the Lamé potential ...

متن کاملSchwarzschild and Synge Once Again
We complete the historical overview about the geometry of a Schwarzschild black hole at its horizon by emphasizing the contribution made by J. L. Synge in 1950 to its clarification. KEY: Schwarzschild solution; Synge; black hole; horizon
متن کاملMeasurement without Theory, Once Again
Bailey and Collins (2011) argue that Greenwood, Seshadri, and Vandenbroucke’s (2005) hypothesis that the baby boom was partly due to a burst of productivity in the household sector is not supported by evidence. This conclusion is based on regression results showing that appliance ownership is negatively correlated with fertility. They also argue that the Amish, who limit the use of modern techn...
