主 题:power mean Seiffert mean inequality
摘 要:In this paper, we find the greatest value p = log 2/(log Tr - log 2) = 1.53.- and the least value q -- 5/3 - 1.66.. such that the double inequality Mp(a,b) 〈 T(a,b) 〈 Mq(a,b) holds for all a, b 〉 0 with a # b. Here, Mp(a, b) and T(a, b) are the p-th power and Seiffertmeans of two positive numbers a and b, respectively.
