The Simplicial EHP Sequence in A1-Algebraic Topology

Kirsten Wickelgren, Ben Williams

We give a tool for understanding simplicial desuspension in A1-algebraic topology: we show that $X \to Ω (S^{1} \land X) \to Ω (S^{1} \land X \land X)$ is a fiber sequence up to homoto…

Classification of problematic subgroups of U(n)

Julia E. Bergner, Ruth Joachimi, Kathryn Lesh +2

We classify p-toral subgroups of U(n) that can have non-contractible fixed points under the action of U(n) on the complex of partitions of complex n-space into mutually orthogonal…

Fixed points of $p$ -toral groups acting on partition complexes

Julia E. Bergner, Ruth Joachimi, Kathryn Lesh +2

We consider the action of $p$ -toral subgroups of $U (n)$ on the unitary partition complex $L_{n}$ . We show that if $H \subseteq U (n)$ is $p$ -toral and has noncontractible fixe…
