This 1987 book examines the approximation of real functions by real rational functions. These are a more convenient tool than polynomials, and interest in them was growing, especially after D. Newman's work in the mid-sixties. The authors present the basic achievements of the subject and also discuss some topics from complex rational approximation.Petrushev, P. P. is the author of 'Rational Approximation of Real Functions (Encyclopedia of Mathematics and its Applications)', published 1988 under ISBN 9780521331074 and ISBN 0521331072.
