关于Yang Bicheng不等式的另一个最佳常数

Another Optimum Constant of Yang Bicheng′s Inequality

对Yang Bicheng不等式进行了再加强,获得了如下不等式:e 1-2n+(4-1 e)/(e-2)1+n1n<e 1-2n+1 11/6(n=1,2,3,…)其中α=(4-e)/(e-2)和β=11/6是最佳常数.

The essay strengthens Yang Bicheng′s inequality and obtains the following inequalitye1-12n+(4-e)/(e-2)1+1nn<e1-12n+11/6(n=1,2,3,…),among which α=(4-e)/(e-2) and β=11/6is the optimum constant.
