Let $\Gamma$ be a group and let $B\Gamma$ denote its classifying space. Assume that $B\Gamma$ is finitely dominated, and denote its finiteness obstruction by $\sigma(B\Gamma)$. Hsi…

Let $X$ be a finitely dominated H-space, meaning a pointed space with a map $X\times X\to X$ whose restriction to $X\vee X$ is homotopic to the folding map. Its finiteness obstruct…
