Young's InequalityIn mathematics, Young's inequality states that if a and b are two positive real numbers and p and q also with 1/p + 1/q = 1 then we have -
Proof: Because log is a concave function, we have -
Because the map exp : R → R+ is strictly monotonically increasing, it follows that ab ≤ ap/p + bq/q. Usage Young's inequality is used in the proof of the Hlder inequality.
