In mathematics two real numbers p q gt 1 displaystyle p q gt 1 are called conjugate indices or Holder conjugates if 1 p 1 q 1 displaystyle frac 1 p frac 1 q 1 Formally we also define q displaystyle q infty as conjugate to p 1 displaystyle p 1 and vice versa Conjugate indices are used in Holder s inequality as well as Young s inequality for products the latter can be used to prove the former If p q gt 1 displaystyle p q gt 1 are conjugate indices the spaces Lp and Lq are dual to each other see Lp space See also editBeatty s theoremReferences editAntonevich A Linear Functional Equations Birkhauser 1999 ISBN 3 7643 2931 9 This article incorporates material from Conjugate index on PlanetMath which is licensed under the Creative Commons Attribution Share Alike License nbsp This mathematical analysis related article is a stub You can help Wikipedia by expanding it vte Retrieved from https en wikipedia org w index php title Conjugate index amp oldid 1155007361, wikipedia, wiki, book, books, library,
