We prove a basic inequality for the $d$-invariants of a splice of knots in homology spheres. As a result, we are able to prove a new relation on the rank of reduced Floer homology under maps between Seifert fibered homology spheres, improving results of the first and second authors. As a corollary, a degree one map between two aspherical Seifert homology spheres is homotopic to a homeomorphism if and only if the Heegaard Floer homologies are isomorphic.

Heegaard Floer同源性和拼接同源性球
我们证明了同源球中一系列结的$ d $不变量的基本不等式。结果,我们能够在Seifert纤维同源球体之间的映射下证明减少的Floer同源性等级上的新关系,从而改善了第一作者和第二作者的结果。推论是,当且仅当Heegaard Floer同源性是同构的时,两个非球面Seifert同源球之间的一个度图才是同胚的同位。
