Thick ideals in equivariant and motivic stable homotopy categories

Ruth Joachimi

We study thick ideals in the stable motivic homotopy category SH(k) and in its subcategories of compact and of finite cellular objects. If k is a subfield of the complex or even th…

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…
