Professor of Computer Sciences and Mathematics (1963)
Ph.D., Basel (Switzerland), 1953.
Before coming to Purdue, Professor Gautschi did postdoctoral work as a Janggen-Pöhn Research Fellow at the National Institute of Applied Mathematics in Rome and at the Harvard Computation Laboratory. He also held positions at the National Bureau of Standards, the American University, the Oak Ridge National Laboratory, and the University of Tennessee. Since coming to Purdue, he has been a Fulbright Scholar at the Technical University of Munich and has held visiting appointments at the University of Wisconsin, Argonne National Laboratory, and Wright-Patterson Air Force Base. He has been a Fulbright Lecturer, an ACM National Lecturer, and a SIAM Visiting Lecturer. He is, or has been, on the editorial boards of SIAM Journal on Mathematical Analysis, Numerische Mathematik, Calcolo, and Mathematics of Computation, and has served as a special editor for Linear Algebra and Its Applications. From 1984 to 1995 he has been the managing editor of Mathematics of Computation and, since 1991, an honorary editor of Numerische Mathematik.
His research interests are in numerical analysis and mainly concern problems relating to classical mathematical analysis. He is interested in the numerical stability of linear difference equations and related computational algorithms, with applications to the accurate computation of special functions of mathematical physics. Recent research interests are the theory and application of continued fractions and constructive methods in orthogonal polynomials. He has contributed to the calculus of variations, the numerical solution of ordinary differential equations, the numerical condition of matrices and algebraic equations, Chebyshev-type quadratures, and numerical Fourier analysis.
