Preface of the Proceedings

In year 1990 the National Science Committee and the Chinese Academy of Sciences (or Academia Sinica) decided to establish a Research Center in the Institute of Systems Science of the Academy. The Center will aim at the study of Mathematics Mechanization} which is closely related to such disciplines vividly developed in recent years like Automated Reasoning, Symbolic Computation, Computer Algebra, et al. We adopted the name of Mathematics Mechanization for the Center which had its origin in works of Hao Wang, one of the pioneers in using computers to the research of mathematics, theorem-proving in particular. This International Workshop on Mathematics Mechanization will be the first one of a series of Workshops bearing the same title. They are aimed at the interchange of views and ideas about the development of related subjects for the sake of world-wide cooperations. The present first Workshop has its theme mainly restricted to algebraic equations solving, both in theories and in applications, for which the importance as well as difficulties have been widely well-acknowledged. More than ten mathematicians and computer scientists beyond China had accepted our invitations and contributed papers to be presented on the Workship. All these papers, as well as those by workers in China proper, have been collected in this Proceedings, to be distributed in the opening day of the Workshop. On behalf of the Center the undersigned would like to express our warm gratitudes to all the contributors, the principal sponsors of the Workshop, viz. the National Natural Science Foundation of China and the Academy, and besides, the International Academic Publishers who takes cares of the fast printing of this volume.
