Webb5 mars 2024 · Figure 1.5. 1: The twin paradox, interpreted as a triangle inequality. A simple and important case is the one in which both m and n trace possible world-lines of material objects, as in figure 1.5. 1. That is, they must both be timelike vectors. To see what form of the Cauchy-Schwarz inequality should hold, we break the vector n down into two ...

The Cauchy-Schwarz inequality Let x and y be points in the Euclidean space Rn which we endow with the usual inner product and norm, namely (x,y) = Xn j=1 x jy j and kxk = Xn j=1 x2 j! 1/2 The Cauchy-Schwarz inequality: (1) (x,y) ≤ kxkkyk. Here is one possible proof of this fundamental inequality. Proof.
