Let $\mathfrak{grt}_{\rm ell}$ be the elliptic Grothendieck–Teichmüller Lie algebra, and let $\mathfrak{krv}^{(1,1)}$ be the Kashiwara–Vergne Lie algebra for a surface of genus $1$…

Let a genus $0$ compact surface be equipped with a group-like expansion arising from a solution to the Kashiwara–Vergne problem, and consider the tensorial description of its Turae…
