WebbThe Cauchy-Schwarz Inequality (also called Cauchy’s Inequality, the Cauchy-Bunyakovsky-Schwarz Inequality and Schwarz’s Inequality) is useful for bounding expected values that are difficult to calculate. It allows you to split E [X 1, X 2] into an upper bound with two parts, one for each random variable (Mukhopadhyay, 2000, p.149).

WebbThis form of the Riesz–Fischer theorem is a stronger form of Bessel's inequality, and can be used to prove Parseval's identity for Fourier series . Other results are often called the Riesz–Fischer theorem ( Dunford & Schwartz 1958, §IV.16). Among them is the theorem that, if A is an orthonormal set in a Hilbert space H, and then.

WebbIn fact, examining this proof we see that equality holds in Cauchy-Schwarz iff the angle between x and y is a multiple of ˇ, or in other words, iff x is a rescaling of y. Thus, we can write the theorem in a stronger form: Theorem 1.3 (Cauchy-Schwarz, v2.0). Given x;y 2Rn, we have (xy)2 (xx)(y y) with equality if and only if x is a rescaling of y.
