Outline of Final Research Achievements

Elements such as circles and polygons were extracted from the Geometric problems described in WASAN book. A specification has been established that describes the relationship between tagged elements as a numeric vector by Java. Geometric similarity evaluation by this descriptive expression also became possible by R. We also construct the new data-base of "SANPOU TENSEI SHINAN" written by "AIDA SANZAEMON YASUAKI" as digital archives. Moreover we made the new software on Geogebra which can describe Problem of Apollonius.

Academic Significance and Societal Importance of the Research Achievements

和算は、江戸時代に花開いた日本独自の数学であり、広く日本国民が数学を趣味として、喜びを持って学んでいた「和算」が限られた研究者のみの研究対象では無く、現代社会において再発掘されるべき存在である事を確認したい。問題検索を可能とする和算書データベースの構築は、まさに「和算」を可能な限り身近にする環境整備の要になるシステムである。
