The Ranks of the Homotopy Groups of a Finite Dimensional Complex
Let $X$ be an
$n$dimensional, finite, simply connected CW complex and set
$\alpha_X =\limsup_i \frac{\log\mbox{ rank}\, \pi_i(X)}{i}$. When
$0\lt \alpha_X\lt \infty$, we give upper and lower bound for $
\sum_{i=k+2}^{k+n} \textrm{rank}\, \pi_i(X) $ for $k$ sufficiently
large. We show also for any $r$ that $\alpha_X$ can be estimated
from the integers rk$\,\pi_i(X)$, $i\leq nr$ with an error bound
depending explicitly on $r$.

Homotopy Decompositions Involving the Loops of Coassociative Co$H$ Spaces
James gave an integral homotopy decomposition of $\Sigma\Omega\Sigma X$,
HiltonMilnor one for $\Omega (\Sigma X\vee\Sigma Y)$, and CohenWu gave
$p$local decompositions of $\Omega\Sigma X$ if $X$ is a suspension. All
are natural. Using idempotents and telescopes we show that the James and
HiltonMilnor decompositions have analogues when the suspensions are
replaced by coassociative co$H$ spaces, and the CohenWu decomposition
has an analogue when the (double) suspension is replaced by a coassociative,
cocommutative co$H$ space.
