本文研究单连通有限CW复形范畴c~,设p为素数或零。对于pr 0和Zo = Q,表示Zp= Z/pZ。空间X与空间Y是p-等价的,如果存在映射f:X~ Y使得f诱导同构:H*(Y; Zp)~ H*(X; Zp).则f称为p-等价。不知道p-等价是否是等价关系,特别是,它是否满足双线性。让我们回想一下,空间K称为p-泛的,如果对于任何给定的p-等价k:X~ Y和任意的映射g:K~ Y,存在映射h:K~ X和存在p-等价f:K--+ K使得下面的图交换到同伦:
Throughout this paper we work in the category c~ of simply connected, finite CW complexes.Let p be a prime or zero. Denote Zp= Z/pZ for pr 0 and Z o= Q. A space X is p-equivalent to a space Y if there exists a map f: X~ Y such that f induces isomorphisms: H*(Y; Zp)~ H*(X; Zp). Then f is called a p-equivalence. It is not known if p-equivalence is an equivalence relation, in particular, if it satisfies symmetricity. Let us recall that a space K is called p-universal [6] if, for any given p-equivalence k: X~ Y and for an arbitrary map g: K~ Y, there is a map h: K~ X and there is a p-equivalence f: K--+ K such that the following diagram commutes up to homotopy:
