Lando–Yang conjecture. The projection $u(D)$ is a linear combination of connected Jacobi diagrams with at most $\tau(D)$ legs. In particular, for any Lie algebra $bfg$ and its asso…

Let $\Lambda$ be Vogel's algebra of three-legged Jacobi diagrams that are antisymmetric under permutations of their legs, with product defined by insertion at a vertex. Generation…

Let $\mathcal{X}^3$ be the space of fixed Jacobi diagrams with three legs, and let $\Lambda\subseteq\mathcal{X}^3$ be the subspace of elements antisymmetric under permutations of t…
