Abstract:

Professor Shunro Watanabe of Japan has been visiting our group since March, 1982. In the past year he has been able, with the support of our group, to develop a major new program for solving in closed from a wide variety of ordinary differential equations. The MACSYMA system uses two large packages for solving ODES. Professor Watanabes approach is to convert most second order ODEs into instances of the so-called P-function. These functions, originally due to Riemann, have been extensively studied by the Japanese mathematician Fukuhara also spelled Hukuhara. For the past year, Watanabe has implemented a package that transforms a large class of equations into P-functions. He has used Kamkes table as a test bed. Several examples from Kamke using this package, are given in Appendix I.
