得到最小值a,γ和最大值β,π,使得对所有a,b〉0,a≠b,不等式成立.这里,Hw(a,b),P(a,b)和L(a,b)分别是两个正数a和b的广义海伦平均,第一类Seiffert平均和对数平均.
We find the least values a,γ and the greatest values,β,τ T such that the inequalities hold for all a, b 〉 0 with a ≠ b. Here, Hω(a, b), P(a, b) and L(a, b) be the generalized Heronian, the first Seiffert and the logarithmic means of two positive numbers a and b, respectively.
