Ambidextrous global spectra and tempered cohomology

William Balderrama, Jack Morgan Davies, Sil Linskens

We introduce generalizations of global equivariant spectra which encode globally equivariant cohomology theories equipped with additional transfers, such as the deflation maps pres…

Total power operations in spectral sequences

William Balderrama

We describe how power operations descend through homotopy limit spectral sequences. We apply this to describe how norms appear in the $C_{2}$ -equivariant Adams spectral sequence, to…

$K$ -theory equivariant with respect to an elementary abelian $2$ -group

William Balderrama

We compute the $R O (A)$ -graded coefficients of $A$ -equivariant complex and real topological $K$ -theory for $A$ a finite elementary abelian $2$ -group, together with all products, tra…

Deformations of homotopy theories via algebraic theories

William Balderrama

We develop a homotopical variant of the classic notion of an algebraic theory as a tool for producing deformations of homotopy theories. From this, we extract a framework for const…

The $C_{2}$ -equivariant $K (1)$ -local sphere

William Balderrama

We compute the $R O (C_{2})$ -graded Green functor $π_{⋆} L_{K U_{C_{2}} / (2)} S_{C_{2}}$ .
