作者： wu WEn-TS■n

The statement of Theorem 1 of the paper "On a Theorem of Leray" in Vol.X, no. 7, 1961, of this iournal should be corrected to take the following form: Theorem 1. Let H be a cohomology theory defined on pairs of normal spaces which possess the strong excision property. Let E be a bicompact Hausdorff space with a finite closed covering F such that each non-empty intersection of sets in F has the same cohomology groups in dimensions up to r as those of a point, then the cohomology group in dimension r of E will be isomnorphic to that of the nerve complex K of the covering F, etc.

作者：吴文俊 Institute of Systems Science Academia Sinica

In a previous paper (cf. [3]) we have pointed out that almost all theorems in ordinary geometry(i.e, ordinary euclidean geometry) are only generically true, or true only under some non-degeneracy) conditions usually not explicitely described in the statement of the theorem. This fact is quite fatal to make the usual euclidean fashion

"爱咋咋地"在汉语中表示一种无所谓、随意或不耐烦的态度和情感,与它结构相类似的诸多格式证明,"爱咋咋地"只是其概括形式的一个变体。通过对以"爱咋咋地"为代表的AVV构式的研究可以揭示汉语更易形成构式的两大原因:表达求简和缺少形式限制(形式自由)。汉语的构式研究可以丰富构式语法理论的内容。

§1. Let ζ={（?）, X, ω} be an S°-bundle or a 2-sheeted covering having a base-connected polytope X, projection ω, and a structural group T consisting of two elements: 1 and t, with t operating without fixed points in （?）. For any coefficient group G, let G（ζ） be the system of local groups in X determined by the homomorphism φ:π1（X, x0）→AutG such that for any α∈π1（X, x0）, φ（α）（g）=+g or -g accord-
