I haveam having some trouble to understandunderstanding the difference between the p$p$-completion and pa $p$-local space. if
If $X$ a simply connected spaces such thatspace has all higher homotopy groups are finitely generated groups, then the p$p$-local approximation $X\rightarrow L_{p}X$ coincides with the $p$-completion $X_{p}^{\wedge}$. Is itthis correct?
Now if $X$ is not simply connected such that the fundamental group is abelian, do we have that $ L_{p}X \simeq X_{p}^{\wedge}$.?
I think it is true if $X$ is a circle, more precisely, $S^{1\wedge}_{p}\sim L_{p}S^{1}\sim K(\mathbf{Z}_{p}^{\wedge},1)$. Am I wrong ?
