摘要

The advantage of this method is that (1,4) yields for θ(x) a differential equation of the first order not involving the function r(x). If we have determined by means of this differential equation the asymptotic behaviour of θ(x), then formula (1.5) gives us immediately by integration the asymptotic behaviour of 2 log r(x). In that case the asymptotic behaviour of θ(x) and r(x) and therefore also of the functions y(x) and y(x), occurring in (1.3), is known.
