Let $e,f,h$ form an $\mathfrak{sl}_2$ triple, and let $\overleftarrow h$ denote the element with reverse characteristic to that of $h$. Suppose $\tilde e,\tilde f,\overleftarrow h$…

Canonical-form conjecture. For $p \geq 4$, there are 10 canonical forms for nonzero $p \times 2 \times 2$ tensors over $\mathbb{F}_2$. For each orbit, the rank and the horizontal…

Let $\mathrm{H}^\star$ be the isotropy group arising from the time-like reduction of a supergravity theory with homogeneous symmetric Special Geometry, and let the associated Lax o…
