One of the fundamental ideas of mathematical analysis is the notion of a function; we use it to describe and study relationships among variable quantities in a system and transformations of a system. We have already discussed real functions of one real variable and a few examples of functions of several variables but there are many more examples of functions that the real world, physics, natural and social sciences, and mathematics have to offer: (a) not only do we associate numbers and points to points, but we as- ciate numbers or vectors to vectors, (b) in the calculus of variations and in mechanics one associates an - ergy or action to each curve y(t) connecting two points (a, y(a)) and (b,y(b)): b Lea ~(y) - / 9 F(t, y(t), y' (t))dt t. J a in terms of the so-called Lagrangian F(t, y, p), (c) in the theory of integral equations one maps a function into a new function b /1, d-r / o. J a by means of a kernel K(s, T), (d) in the theory of differential equations one considers transformations of a function x(t) into the new function t t f f( a where f(s, y) is given. 1 in M.

From the reviews: "This book is suitable as a text for graduate students. Photographs of Banach, Frechet, Hausdorff, Hilbert and some others mathematicians are imprinted in order to involve [the reader] in the work of mathematicians."-Zentralblatt MATH "This volume is an English translation and revised edition of a former Italian version published in 2000. ... This nice book is recommended to advanced undergraduate and graduate students. It can serve also as a valuable reference for researchers in mathematics, physics, and engineering." (L. Kerchy, Acta Scientiarum Mathematicarum, Vol. 74, 2008) "The book 'M. Giaquinta, G. Modica: Mathematical Analysis. Linear and Metric Structures and Continuity' is a lovely book which should be in the bookcase of every expert in mathematical analysis." (Dagmar Medkova, Mathematica Bohemica, Issue 2, 2010) "This book offers a self-contained introduction to certain central topics of functional analysis and topology for advanced undergraduate and graduate students. ... the clear and self-contained style recommend the book for self-study, offering a quick introduction to a number of central notions of functional analysis and topology. A large number of exercises and historical remarks add to the pleasant overall impression the book leaves." (M. Kunzinger, Monatshefte fur Mathematik, Vol. 157 (2), June, 2009)
