Suspension Homotopy of $(n - 1)$ -connected $(2 n + 2)$ -dimensional Poincaré Duality Complexes

Pengcheng Li, Zhongjian Zhu

We study the homotopy decompositions of the suspension $Σ M$ of an $(n - 1)$ -connected $(2 n + 2)$ dimensional Poincaré duality complex $M$ , $n \geq 2$ . In particular, we completely deter…

Descent of splendid Rickard equivalences in $GL_{n} (q)$

Xin Huang, Pengcheng Li, Jiping Zhang

Let $n$ be a positive integer and $q$ a prime power. We prove that a refined version of Broué's abelian defect group conjecture holds for unipotent $ℓ$ -blocks of $GL_{n} (q)$ …
