简介：本文在无穷维空间引入(E0，E)型渐近光滑映射的概念，研究了其基本性质和变为E中渐近光精映射的条件，我们证明了(E0，E)型吸引子存在性定理和(E0，E)型吸引子转化为E中吸引子的条件定理，所有结果都应用于一类耗散波方程新近性态的研究．

简介：左R-模M称为Eω-内射模,如果对环R中任意的ω阶Euclid理想I来说,任何R-模同态能够拓展为R-模同态。左R-模M称为Eω-投射模,若对环R中任意的ω阶Euclid理想I和任何R-模同态f∈HomR（M,R/I）,存在R-模同态g∈HomR（M,R）使得f=πg,其中π是自然同态。本文证明P和Q均是Eω-投射模当且仅当PQ是Eω-投射模。进而,又证明了每一个左R-模是Eω-投射的当且仅当每一个左R-模是Eω-内射。
