Chromatic higher semiadditivity via redshift

Shay Ben-Moshe

We give a new proof of the $\infty$ -semiadditivity of $K (n)$ -local spectra. The proof proceeds by induction on the height via algebraic K-theory, utilizing recent advances in the r…

Higher Semiadditivity in Transchromatic Homotopy Theory

Shay Ben-Moshe

We study the compatibility of higher semiadditivity across different chromatic heights. We prove that the categorified transchromatic character map assembles into a parameterized s…

Chromatic Cardinalities via Redshift

Shay Ben-Moshe, Shachar Carmeli, Tomer M. Schlank +1

Using higher descent for chromatically localized algebraic $K$ -theory, we show that the higher semiadditive cardinality of a $π$ -finite $p$ -space $A$ at the Lubin-Tate spectrum $E_…
