Heal, editor, Topological Social Choice: With 45 Figures (Social Choice and Welfare; vol. 14, no. 2, 1997), Berlin: Springer-Verlag, →DOI, →ISBN, page 110:To get an intuitive feeling for the characteristics of $H'$-spaces, it is instructive to consider an important class of such spaces, the suspensions. The suspension of an arbitrary topological space $Y$ is defined to be the quotient space of $Y\times I$ where $Y\times 0$ is identified to one point and $Y\times 1$ is identified to another point. For example, the suspension of a circle is a cylinder with the two ends collapsed into one point each; in other words, a space homeomorphic to a sphere.
* (topology) A function derived, in a standard way, from another, such that the instant function’s domain and codomain are suspensions of the original function’s.

The homotopy category of any pointed model category acquires a suspension functor denoted by $\Sigma$. It turns out that ${\text{Ho}}(M)$ is a pre-triangulated category in a natural way […]. When the suspension is an equivalence, $M$ is called a stable model category, and in this case ${\text{Ho}}(M)$ becomes a triangulated category […].
