On the homotopy classification of spaces by the fixed loop space homology

Let $R\subseteq \mathbb{Q}$ be a subring of the rationals and let $p$ be the least prime (if none, $p=\mathrm{\infty }$) which is not invertible in $R\mathrm{.}$ For an $R$-local $r$-connected $CW$-complex $X$ of dimension $\leq \min(r+2p-3,rp-1), r\geq 1, $ a complete homotopy invariant is constructed in terms of the loop space homology $H_{\ast }(\mathrm{\Omega }X)\mathrm{.}$ This allows us to classify all such $R$-local spaces up to homotopy with a fixed loop space homology.
