Linked from

The 36 pages that link to Cauchy–Schwarz inequality, each with the reason it gives.

• Cauchy sequenceCompared with: Its shared name can distract from the separate role of Cauchy sequences.

• Jensen's inequalityCompared with: It gives a different route to moment bounds, with different assumptions and equality cases.

• Hölder's inequalityCompared with: It is the special case of Hölder's inequality with both exponents equal to two.

• Algebraic identityCompared with: Unlike an identity, it gives a bound that becomes equality only in special cases.

• Chebyshev's sum inequalityCompared with: It bounds products without requiring the sequences to share a monotone ordering.

• Minkowski inequalityCompared with: It is the p = 2 case of Hölder’s inequality, a key proof tool for Minkowski.

• Schur's inequalityCompared with: Cauchy–Schwarz controls inner products; Schur exploits cyclic differences and nonnegative variables.

• Nesbitt's inequalityCompared with: Cauchy–Schwarz proves Nesbitt immediately, but applies to far more general vectors and settings.

• Law of total varianceCompared with: Unlike this exact variance identity, it gives a bound rather than an equality.

• Young's inequality for productsCompared with: It bounds an inner product, whereas Young's inequality bounds a scalar product by powers.

• Abel's inequalityCompared with: It bounds products through squared magnitudes, not cumulative sums and monotone weights.
