Let $d4d8_p$ be the collection of symbols that are bounded Schur multipliers of the Schatten–von Neumann class $d4d4_p$, and let $d4d8_p^{\mathrm{cb}}$ be the collection of symbols…

Schur-ideal perp conjecture. The perp of this Schur ideal is not a semi-algebraic subset of $\mathbb{R}^3$.

Conjecture. The following are equivalent:

Let $G$ be a group. An AI-automorphism of $G$ is an automorphism that induces inversion on $G/G'$. The group functors $\tau(G)$ and $\tilde K(G,3)$ are the two groups associated wi…
