$H Z /4$ is not an $E_{2}$ -Thom Spectrum over the $2$ -Complete Sphere Spectrum

Mattie Ji

For any prime number $p$ , the classic Hopkins-Mahowald theorem asserts that $H Z / p$ is an $E_{2}$ -Thom spectrum over the $p$ -complete sphere spectrum. Kitchloo exten…

Tensor Product $K$ -theory is Rational Algebraic $K$ -theory

Amartya Shekhar Dubey, Mattie Ji

For a commutative ring $R$ with unity, its algebraic $K$ -theory space $K (R)$ may be obtained by group-completing the symmetric monoidal category of finitely generated free $R$ -modu…

Quantum Cellular Automata: The Group, the Space, and the Spectrum

Mattie Ji, Bowen Yang

Over an arbitrary commutative ring $R$ , we develop a theory of quantum cellular automata. We then use algebraic K-theory to construct a space $Q (X)$ of quantum cellular au…
