Summary: | 碩士 === 淡江大學 === 數學學系碩士班 === 94 === If x , y are distinct positive numbers, then
Mp= Mp (x , y)
is called the power mean of x and y .
L = L (x , y)
is called the Logarithmic mean of x and y .
Chang[2]has proved that :
If L < Mq holds for some q such that q<1/3 ,as well as Mp < L holds for some p such that p>0 under certain restrictions on x and y 。.
We shall prove that L < Mq holds for some q such that q <1/6 , as well as L > Mp holds for some p such that p > 0 under certain restrictions on x and y .
