Box 1346 Ann Arbor, Ml 48106- 1346 ABSTRACT I will consider the influence of Chinese mathematics on Seki Kowa. For this purpose, my thesis is constructed in four parts, introduction, I the studies of editions; Shu Shn Jin Zhang and Yang Uni S u m Fa, II the conception and extension of method for making magic squares, and 1 the analysis for solving indeterminate equations. In the introduction, I will explain some similarities between Chinese mathematics in the Song dynasty and Seki Kowa's works. It will become clear that the latter was influenced by Chinese mathematics. Then I introduce some former opinions concerning which Chinese mathematical book influenced him. I shall show that two Chinese mathematical books, Shn Shn Jin Zhang and Yang Hni S u m Fa, are particularly important. Some Chinese mathematical books were republished and studied by Japanese mathematicians, but these two books were not accessible to Japanese mathematicians. Thus we must study them for considering questions of influence. I will consider two subjects, the treatment of magic squares in Yang Hni Snan Fa in chapter H and the method of solving indeterminate equations in Shn Shn Jin Zhang in chapter M. Before considering the contents of these subjects, we must know more about the available versions of these two books in chapter I , otherwise we cannot know whether Seki Kowa could have obtained them. It seems certain that Seki Kowa studied the Yang Hni Snan Fa, but I camot know whether he studied the Shn Shn Jin Zhang. However, Seki Kowa’s method of solving indeterminate equations is very similar to that of Qin Jiushao, especially when their methods of changing negative constants into positive are similar. Thus I would like to propose that Seki Kowa studied the Chinese method of solving indeterminate equations. - 2 - ACKNOWLEDGEMENTS My first debt of gratitude is to my supervisor, Dr. Christopher Cullen, whose unfailing helpfulness and encouragement made this thesis possible. Members of the Needham Research Institute, Dr. Joseph Needham, Prof. Ho Peng- Yoke, Dr. Huang Xingzong and other menbers, were kind to help my research. When I studied history of mathematics at Beijing Normal University, Prof. Bai Shangshu very kindly guided me. At least in spirit he can also be regarded as a supervisor of this thesis. I would like to thank two researchers who corrected my English carefully, Mr. Craig Rodine who is studying history of mathematics and Mr. Paul Charity, mathematician. Of course, all errors and omissions are my responsibility alone. Finally, I would like to thank the Anglo-Daiwa Foundation for financial support. - 3 ~ CONTENTS ABSIRACT.................................................................. 2 ACKN0WITIX2MMS............................................................................................................ 3 INTRODUCTION (1) Aims of this thesis ...................................... 9 (2) Biographical study of Seki Kowa............................ 10 (3) Similarity between Chinese mathematics and Japanese mathematics * • 16 (4) Opinions of how Chinese mathematics influenced Seki K o w a ...... 19 (a) Opinions that Seki Kowa studied Chinese Mathematics * * * • 19 (b) Opinion concerning the S u m Xus Qi Meng {Introduction to Mathematical Studies)......... 21 (c) Opinion concerning the Ce Yuan Hai jing (Sea Mirror of Circle Measurement)............ 22 (d) Opinion concerning the Zhui Shu (Bound Methods)......... * .................. 23 (e) Opinion concerning the Yang Hni Sum-Fa (Yang Hui's Method of Computation)............ 24 (f) New Opinion; opinion concerning the Shu Shu Jiu Zhang (Mathematical Treatise in Nine Sections)....... 25 N o t e s .................... * ................................26 - 4 - [ : THE STUDY OF EDITIONS (1) The Shn.

In the case of Japan, it was introduced into the country two times. The first time was in the eigjhth century, when many mathematical arts were introduced and taught in the University, but Japanese mathematicians only imitated the work of Chinese authorities, and its level was limited. The second time was at the aid of the sixteenth century— at which point, Japanese mathematicians applied Chinese mathematics, and were to produce brilliant achievements. It is
