一个Lefschetz型重合定理

A Lefschetz type coincidence theorem

Peter Saveliev

摘要:

给出了从任意拓扑空间X到流形Y的两个映射f,g:X->Y的一个Lefschetz型重合定理:I(f,g)=L(f,g),重合指数等于莱夫谢茨数.因此,如果L(f,g)不等于零,则X中存在x,使得f(x)=g(x)。特别是,该定理包含(i)X、Y流形和(ii)具有非循环纤维的f的一些众所周知的重合结果。

英文摘要:

A Lefschetz-type coincidence theorem for two maps f,g:X->Y from an arbitrary topological space X to a manifold Y is given: I(f,g)=L(f,g), the coincidence index is equal to the Lefschetz number. It follows that if L(f,g) is not equal to zero then there is an x in X such that f(x)=g(x). In particular, the theorem contains some well-known coincidence results for (i) X,Y manifolds and (ii) f with acyclic fibers.
