Carleman's inequality
The Carleman 's inequality, named after the Swedish mathematician Torsten Carleman, is an elementary inequality of analysis. It says that a number of geometric means of a sequence is bounded by a constant multiple of the row from the top. More specifically, it states that the Euler number is the smallest constant that satisfies as many times this barrier.
The Carleman inequality was first published in 1923 by Torsten Carleman.
Set
Statement
Let be a sequence of real, non- negative numbers. Denote the Euler number. Then:
Here, the smallest number that satisfies this statement.
Evidence
Because is ( telescopic sum )
And follows
And this is after the AM- GM inequality
Variants
For a function with the following continuous variant of Carleman 's inequality holds:
