WebAn Improved Discrete Hardy Inequality Matthias Keller, Yehuda Pinchover, and Felix Pogorzelski Abstract. In this note, we prove an improvement of the classical discrete Hardy inequality. Our improved Hardy-type inequality holds with a weight w which is strictly greater than the classical Hardy weight w H (n ):= 1/(2n )2,wheren N . WebApr 23, 2024 · The classical discrete Hardy's inequality asserts that If ( a n) n = 1 ∞ is a sequence nonnegative real numbers not identically to zero, then ∑ n = 1 ∞ ( a 1 +... + a n n) p ≤ ( p p − 1) p ∑ n = 1 ∞ a n p.
