    1. 平坦とは限らないトーラスにおいてWD作用素を定式化して,トーラスに正スカラー曲率計量が存在しないことを組み合わせ論的に証明すること.
    2. 一般のリーマン多様体でWD作用素を定式化して,特に四次元多様体のとき,ロホリンの定理を組み合わせ論的に証明すること.
    3. 一般の四次元リーマン多様体でWD作用素を用いて,非線型方程式のザイバーグ=ウィッテン方程式を組み合わせ論的に再定式化すること.
    今年度も,前年度までに引き続き,境界付き多様体の指数とドメインウォールフェルミオンとの関係について考察した.物理的にはアノマリーの考察に相当する.最初に得られたのはAPS指数のときで,次が mod 2指数のときで,現在は複素フェルミオンのときを引き続き考えている.しかし,めざましい進展は得られなかったので,物理的応用も研究することにして,そちらでは結果が出た.論文準備中である.さらに,派生研究として,反自己双対計量のモジュライ空間の向き付けについてさらに考察した.K3曲面のとき,反自己双対計量のモジュライ空間が向き付け可能ではないという大変興味深い結果を得ていたが,その証明を見直し,現在は一般の多様体の向き付けの条件を求めるために,KR指数を計算している.ほぼ計算は完了した.また,格子指数の連続極限の存在について証明を大幅に簡略化した.結果としてウィルソン項の数学的位置付けがさらに明確になった.
    当初の計画通りにおおむね順調に進展しており,さらに派生研究もある.
    今後は,複素フェルミオンを引き続き考えるとともに,格子指数の応用を探っていきたい.また,ウィルソン項の役割をさらに突き詰めることによって,格子指数への透明な理解を目指す.おそらくそれはザイバーグーウィッテン理論への応用もあると考えている.

    I have constructed a monopole map over the universal covering space of a compact oriented smooth four manifold. We apply the infinite dimensional Bott periodicity by Higson-Kasparov-Trout. In particular its degree was given when the linearized map is isomorphic, as an element in the equivariant E theory. It produces a homomorphism between K group of C* algebras related to the group ring. It corresponds to a covering version of the Bauer-Furuta degree.
    As an application, we proposed an aspherical 10/8 inequality for spin classifying 4 manifolds. We have also verified that it certainly holds for large class of 4 manifolds which includes complex minimal surfaces of general type.

    We have investigated the scope of Witten localisation techniques:
    First, we studied the relation between the index on manifolds with boundary and domain wall fermions, inspired by lattice gauge theory; and we derived a formula expressing the Atiyah-Patodi-Singer index interms of the eta invariants of domain wall fermion Dirac operators. We also studied mod 2 extensions.
    Second, we have studied the orientation of moduli spaces of anti-self-dual metrics.

    My mathematical interests include Donaldson theory and Seiberg-Witten theroy in four-manifold topology. Especially, I am interested in non-compactness phenomena of the moduli spaces of instantons.
    I proved an optimal asymptotic growth of the diameters of the moduli spaces of instantons with respect to the instanton number for the standard 4-sphere.

    On a compact manifold with very general singularities, we have studied the Yamabe problem and have established a generalization of Aubin’s inequality for Yamabe constants. When the inequality is strict, we have proved the existence of singular Yamabe metrics.
    When the equality of the inequality holds, we have constructed an example of singular manifolds which have not singular Yamabe metrics. For an edge-cone Einstein metric on a smooth manifold, we have constructed an appropriate family of smooth metrics with Ricci curvature bounded below by the Einstein constant. As a corollary, we have obtained an estimate of the Yamabe invariant from below by using the existence of edge-cone Einstein metrics.

    今年度はブローディ曲線の全体がなす空間の平均次元を研究した.
    京都大学の塚本真輝氏との共同研究である.
    プローディ曲線とは,複素平面から複素射影空間へのリプシッツ正則写像のことであり,その全てを集めた空間は無限次元になる.この無限次元空間の幾何学を研究した.
    正則写像とはコーシー=リーマン方程式の解のことであるが,コーシー=リーマン方程式とゲージ理論における反自己双対方程式には様々なアナロジーが成り立つ.
    この研究もそのアナロジーの一環として捉えることができる.
    平均次元とは,「無限次元空間の次元」としてグロモフが1999年に導入したコンパクト力学系の位相不変量である.
    例えば,N次元閉球の両側無限直積にはコンパクト離散力学系の構造が自然に入るが,その平均次元はちょうどNになる.
    コンパクト力学系の位相不変量には位相的エントロピーもあるが,平均次元はその位相的エントロピーの拡張になっている.位相的エントロピーが数え上げの力学系化だとすれば,平均次元は次元の力学系化である.
    さて,ブローディ曲線の全体がなす空間には,広義一様収束の位相を入れる.
    このとき,函数論における一様族の議論によって,この空間はコンパクトになるとわかる.
    また,ブローディ曲線の全体がなす空間には,複素数のなす群が,定義域へのずらしとして,自然に作用する.
    従って,ブローディ曲線の全体がなす空間はコンパクト力学系である.
    よって,その平均次元を考えることができる.
    我々の主定理は,その評価であり,有理型函数の場合には正確な値を求めた.
    これはリーマン=ロッホの定理の無限次元版と言うことができる.
