International Journal of Mathematical Education in Science and Technology, 1994
Our aim is to present a completed form of Young's inequality. We will give an elementary analytic proof of this inequality by the application of the mean value theorem for integrals known from a first course in real analysis. Moreover, to facilitate understanding, the heuristic strategy of analogy, which is a constructive source of discovery, will be ...

Weighted Young Inequalities for Convolutions
Southeast Asian Bulletin of Mathematics, 2003Let \(1 < p, q < \infty\) and let \(u\) and \(v\) be weighted functions on \(\mathbb R^n\). The aim of the paper is to find sufficient conditions for the validity of the inequality \[ \Bigl(\int_{\mathbb R^n} (g \times f)^q (x)\, u (x) \, dx\Bigr)^{1/q} \leq C \| g\| _X \Bigl(\int_{\mathbb R^n} f (x)^p \, v (x) \, dx\Bigr)^{1/p} \] for all measurable ...

Let p, q > 0 satisfy 1/p + 1/q = 1. We prove that for any pair A, B of n × n complex matrices there is a unitary matrix U, depending on A, B, such that $$U*\left| {AB*} \right|U \leqslant {\left| A \right|^p}/p + {\left| B \right|^q}/q.$$
