WebYoung's inequality states that if p,q p,q are positive reals satisfying \frac {1} {p}+\frac {1} {q}=1 p1 + q1 = 1, then ab \leq \frac {a^p} {p}+\frac {b^q} {q} ab ≤ pap + qbq for all nonnegative reals a,b a,b. It follows from the concavity of the logarithm function and Jensen's inequality; in particular, Webconsists of only one term, so the Schwarz inequality in (3) becomes an equality. A simple example is given with 2×2 matrices: A = 1 0 0 0 ... If one is interested in characterizing cases of equality for the matrix H¨older inequality, one has to check whether hei,gji = αhfi,hji, as stated above, and also

Web1 Aug 2024 · There is a generalization of Cauchy Schwarz inequality from Tripathi [1] that says that: V a r ( Y) ≥ C o v ( Y, X) V a r ( X) − 1 C o v ( X, Y) in the sense that the diference …
Web1 Apr 1999 · The inequality is sharp if x ′ a + y ′ b =0 w.p. 1, for some (a,b)∈ R p × R q; i.e. if the distribution of ( x,y) puts all its mass in some proper linear subpspace of R p+q. Also notice that when p = q =1, i.e. when we are dealing with random variables, the above result reduces to the usual Cauchy-Schwarz inequality; i.e. ( E xy) 2 ≤ E x 2 E y 2.
