The $\mathfrak{sl}_2$-algebra conjecture for multiple Eisenstein series. These maps should be well-defined $\mathbb{Q}$-linear maps on $\mathcal{E}$, should be derivations, and sho…

Let $\pi:\overline{J}_C\to B$ be as in the motivic Beauville decomposition conjecture, and let $\operatorname{Corr}^k_B(\overline{J}_C,\overline{J}_C)$ denote the degree-$k$ relati…

Let the center be identified with the geometrically constructed cohomological model, equipped with the $\mathfrak{sl}_2$-action obtained from the Lefschetz construction on the para…
