In the year 1996 Eguchi constructed a large class of 4 dimensional superconformal field theories starting from the Seiberg-Witten exact solutions of N=2 supersymmertic gauge theories and adjusting their parameters to critical values. He then classified these conformal theories based on their critical exponents and has shown that the classification follows after the pattern of the A-D-E Lie algebra.In the year 1997 Eguchi studied the topological string amplitudes on arbitrary Kahler manifolds M and has shown that they are annihilated by an infinite number of differential operators L_nL_nZ=0, n=-1,0,1,2, ・・・ (1)and these operators form a Virasoro algebra[L_n, L_m]= (n-m) L_<n+m>+(X (M) )/ (n^3-n) delta_<n+m, 0> (2)Here X (M) is the Euler number of M.By representing the Virasoro operators in terms of free fields he further showed that the topological string amplitudes are described by bL_<even> free bosons and bL_<edd> free fermions. Here b_<**> (M) are the Betti numbers of M.

在1996年，埃古奇（Eguchi）从n = 2超对称仪表理论的seiberg-witten精确解决方案开始，建造了4个维度的超符合场理论，并将其参数调整为临界值。然后，他根据其关键指数对这些形式的理论进行了分类，并表明分类遵循A-d-e的模式。在1997年，Eguchi在任意Kahler上的拓扑弦放大器研究了M. a Virasoro algebra[L_n, L_m]= (n-m) L_<n+m>+(X (M) )/ (n^3-n) delta_<n+m, 0> (2)Here X (M) is the Euler number of M.By representing the Virasoro operators in terms of free fields he further shown that the topological string amplitudes are described by bL_<even> free bosons and bl_ <edd>免费费米子。这里b _ <**>（m）是M的Betti数字。
