非单位κ-代数的局部循环同调及切除定理
LOCAL CYCLIC HOMOLOGY OF NONUNITAL k-ALGEBRA AND EXCISION THEOREM
【摘要】 本文定义了单位过滤k-代数和非单位过滤k-代数的局部Hochschild同调和局部循环同调,给出 了它们之间的局部Connes长正合列.进一步利用循环同调来计算局部循环同调的短正合列公式,讨论 了关于过滤k-代数局部循环同调的切除定理.
【Abstract】 This paper defines the local Hochschild homology and local cyclic homology on both unital k-algebras and nonunital k-aglebras, and finds the local Connes’ long exact sequence between them. By using the formula of cyclic homology to calculate local cyclic homology, the author discusses the excision theorem in local cyclic homology.
