Outline of Final Research Achievements

For complex manifolds X and Y (resp. real algebraic varieties X and Y), let Hol(X,Y) (resp. Alg(X,Y)) denote the space of all holomorphic maps (resp. regular maps) from X to Y. When we denote by Map(X,Y) the space of continuous maps from X to Y, we consider what dimension the finite dimensional subspace Hol(X,Y) (resp. Alg(X,Y)) approximates the homotopy type of the infinite dimensional space Map(X,Y). This problem is usually called the Atiyah-Jones-Segal conjecture. In this research we mainly consider the case for the Riemann surface X (resp. 1 dimensional sphere) and a toric variety Y. We also investigate the analogues problem for several related spaces defined from the resultants.

Academic Significance and Societal Importance of the Research Achievements

無限次元写像空間Map(X,Y)のホモトピー型の研究は, ゲージ理論等の数理物理とも密接に関連して重要な基本問題である. しかしこの空間は無限次元の巨大な空間であり取り扱いが厄介である. そこで, この空間を取り扱いやすい適当な有限次元部分空間(たとえば, Hol(X,Y)やAlg(X,Y))でどの次元までそのホモトピー型を近似できるかを調べることは極めて自然であり, 興味の持たれる問題である. 本研究の成果は, 数理物理への応用の観点からも重要で社会的意義があり, さらに学術的意義もあると思われる.
