取V的光滑部分的L 2-上同调H&RQ(V Sing V)和右边光滑部分的L 2 a-上同调H&I q(V Sing V),得到非光滑变种V。这里的“L 2-上同调”是在De Rham的书[DR]的意义下的,而V的黎曼(或Hermitan)度量是由V在射影空间中的嵌入而诱导的。当M是Hodge分解中(0,q)型项的维度的交错和时,M的算术亏格,
to nonsmooth varieties V by taking the L 2 -cohomology H&rq (V Sing V) of the smooth part of V on the left and the L 2 a-cohomology H&i q (V Sing V) of the smooth part on the right. Here" L 2 -cohomology" is in the sense of de Rham's book [dR] and the Riemannian (or Hermitan) metric on V Sing V is that induced from the imbedding of V in projective space. When M is smooth the alternating sum of the dimensions of the terms of type (0, q) in the Hodge decomposition, the arithmetic genus of M,
