Brezinski C. Continued Fractions and Pade Approximants

1990, North-Holland, 331 p.Pade approximants and continued fractions are typical examples of old domains (since continued fractions can be traced back at least to Euclid's g.c.d. algorithm more that 2000 years ago) which are nou in full vitality. Thi is due to their numerous applications in number theory, cryptography, statistics, numerical analysis, special functions, digital filtering, signal processing, fractals. etc. This renewal of interes is also due to their intimate connections with other important topics such as orthogonal polynomials, rational approximation, Gaussian quadraturesm extrapolation and convergence acceleration methods, solution of differential equations and so on.
Since the subject is very rapidly developing, it seemed that a book gathering carefully selected papers presenting the last results would be of interest. This book comes from a special issue of the IMACS journal Applied Numerical Mathematics(vol.
4. numbers 2-4, June 1988) plus some new contributions specially written for it. All the papers contained in the book are original and important.On the asymptotic behavior of continued fractions.
