WebMar 13, 2024 · Jensen’s inequality can be used to derive many other classical inequalities, typically applied to the exponential, logarithm or powers. Arithmetic, harmonic, and geometric means. For X with positive real values, we have: E[X] ⩾ exp(E [log(X)]) and E[X] ⩾ 1 E [1 X], which corresponds for empirical measures to classical inequalities between ... WebJun 5, 2024 · Inequality (1) was established by O. Hölder, and (2) by J.L. Jensen [2] . With suitable choices of the convex function $ f $ and the weights $ \lambda _ {i} $ or weight function $ \lambda $, inequalities (1) and (2) become concrete inequalities, among which one finds the majority of the classical inequalities.

WebJensen's formula is an important statement in the study of value distribution of entire and meromorphic functions. In particular, it is the starting point of Nevanlinna theory , and it often appears in proofs of Hadamard factorization theorem , which requires an estimate on the number of zeros of an entire function.
