內容提要

It is oftereally difficult to trace the origiof a familiar inequality. It is quite likely to occur first as aauxiliary proposition， oftewithout explicit statement， ia memoir ogeometry or astronomy; it may have beerediscovered， many years later， by half a dozedifferent authors; and no accessible statement of it may be quite plete. We have almost always found， evewith the most famous inequalities， that we have a little new to add. We have done our best to be accurate and have giveall references we can， but we have never undertakesystematic bibliographical research. We follow the mopractice， whea particular inequality is habitually associated with a particular mathematicians name; we speak of the inequalities of Schwarz， HSlder， and Jensen， though all these inequalities cabe traced further back; and we do not enumerate explicitly all the minor additions which are necessary for absolute pleteness. We have received a great deal of assistance from friends. Messrs G. A. Bliss， L. S. Bosanquet， R. Courant， B. Jessen， V. Levin， R. Rado， I. Schur， L. C. Young， and A. Zygmund have all helped us with criticisms or original contributions. Dr Bosanquet， Dr Jessen， and Prof. Zygmund have read tho proofs， and corrected many inaccuracies. Iparticular， Chapter III has beevery largely rewritteas the result of Dr Jessens suggestions. We hope that the book may now be reasonably free from error， ispite of the mass of detail which it contains.
