Abstract

Let f be a positive strictly increasing logarithmic convex (or logarithmic concave) function on (0, 1], then, for k being a nonnegative integer and n a natural number, the sequence is decreasing in n and k and has a lower bound 10 ƒ(t)dt. From this, some new inequalities involving are deduced.
