Central-extension bounded-locality conjecture. The locality function $S_{\widehat{\goth L},\,\cal G\cup\cal M}$ is also uniformly bounded.

Let $A=\mathbb{C}[x^{\pm1},u\mid u^2=P(x)]$, where $P(x)\in\mathbb{C}[x]$ is palindromic of even degree $2r$ with simple roots. Let $A/\partial A$ denote the quotient by exact deri…

Let $\operatorname{Ann}$ be the annulus semigroup and let … be the stated central extension. Diffeological universality conjecture. This extension is a universal central extension…

Universality conjecture. This central extension is a universal central extension. The claim concerns universality in the category of central extensions of the annulus semigroup. Th…

Let $F$ be a field of characteristic different from $2$. Let $J$ be a Jordan algebra over $F$ generated by idempotents, and let a $\mathcal{J}(\frac{1}{2})$-axial central extension…
