The following articles represent the contributed and invited lectures given at the Symposium on Constructive and Computational Methods for Differential and Integral Equations held at Indiana University, Bloomington, Indiana, from February 17-20, 1974. The Symposium was organized through the Research Center for Applied Science at Indiana University under the sponsorship of the Air Force Office of Scientific Research Grant No. 74-2674.

One of the main objects of this Symposium was to collect together those mathematicians working in the general area of constructive and computational methods for solving differential and integral equations in order to prepare a survey of recent developments in this important area of applied mathematical research. Such a survey would have the aim of not only coordinating the work of the active researchers in this area, but would also supply a means through which applied mathematicians and engineers could become more acquainted with the new methods now available for solving problems they may be presently grappling with unsuccessfully. The following collection of addresses therefore contains both reviews and discussions of current problems and it Is hoped they will provide a beginning towards accomplishing the long range objectives of the Symposium.
