Outline of Research at the Start

包括的グレブナー基底系の概念をmixed moduleを扱えるように拡張し、計算代数をもちい特異点分類のための具体的なアルゴリズムを構築する。また、それを特異点の分類(A, K, C, R)同値、KB同値、(VK, VR)同値、あるいはより一般的な同値関係(A[\rho(G)], K[\rho(G)])、さらにそれらの同変な場合、等に組織的に適用することにより、数学あるいは諸科学への特異点論の応用を推し進めること、また、一般論構築の立場からはどのような一般論が望ましいかを再考することを目標とする。

Outline of Final Research Achievements

We extended the concept of comprehensive standard systems for modules to mixed-modules and we develop a concrete algorithm to compute it. We apply the algorithm to classification problems of singularities relative to A, K, C, R, and A[G], K[G]-equivalences. We apply the result to various fields including multi-objective optimization problems.

Academic Significance and Societal Importance of the Research Achievements

本研究の多目的最適化への応用の結果は、その後、共著者の濱田らによって、滑らかとは限らない強凸問題に一般化され、ゲーム開発等に広く応用されている。
本研究はKirkのTransversalをより効率よく、一般的な分類に推し進め、成果である特異点分類のためのソフトウェアは、次世代の特異点研究の必須の道具となると期待される。
