    昨年度と同じ問題を,よりKK理論的な観点から研究した.その問題のモデルはKasparovの結果であるが,それは非コンパクト多様体に局所コンパクト群がproperかつcocompactに作用しているとき,Dirac作用素dの解析的同変指数が定義され,それが,dが作るKホモロジー群の元[d]をdescent homomorphismで送ったものと,群作用からきまるある標準的なKK群の元[c]のKasparov積(Assembly mapによる[d]の像と呼ぶ)で書けることを主張する.昨年度の成果は,Dirac作用素が作るLT同変Kホモロジー群の「元」[D]を(Kホモロジー群の元としてではなくHilbert空間と作用素の組として)構成し,それの素朴な意味でLT同変解析的指数を計算したことにあるが,今年度はその結果をよりKasparovの結果に平行するような形で定式化し直し,Assembly mapの構成に必要なもの構成した.より詳しく言うと,「無限次元空間の関数環のLTによるねじれのない接合積」を新たに構成し,それと昨年構成したLTのねじれ群C^*環のKK群の元として,「[D]のdescent homomorphismによる像」と[c]に対応するK群の元を,(仮想的ではなく本当に)KK群の元として構成し,それらのKasparov積(「Assembly mapの像」と呼べるもの)を計算した.また,解析的指数をKasparovの定義に沿うようにKK群の元として定式化しなおし,「[D]のAssembly mapの像」と一致することを示した.この結果は,Kasparovの結果の無限次元版と言え,論文[Doman Takata:LT-equivariant Index from the Viewpoint of KK-theory]としてarXivで発表してある.
