A multiplicative universal property for real algebraic $K$ -theory

Hadrian Heine, Markus Spitzweck, Paula Verdugo

We prove that the real $K$ -theory functor is lax symmetric monoidal. Moreover, it is initial among those real functors $Wald_{\infty}^{gd} \to Sp^{C_{2}}$ that a…

An equivalence between two frameworks for real algebraic K-theory

Hadrian Heine, Markus Spitzweck, Paula Verdugo

We prove an equivalence between the real $K$ -theory genuine $C_{2}$ -spectra of Calmès et al. for Poincaré $\infty$ -categories and the one of the authors of this work for Waldhausen $…

Infinity categories with duality and hermitian multiplicative infinite loop space machines

Hadrian Heine, Alejo Lopez-Avila, Markus Spitzweck

We show that any preadditive infinity category with duality gives rise to a direct sum hermitian K-theory spectrum. This assignment is lax symmetric monoidal, thereby producing E-i…
