Asai–Iyama's g-tameness and E-tameness conjecture for Jacobi-finite QPs

Let (Q,W)(Q,W) be a non-degenerate Jacobi-finite quiver with potential, and let J(Q,W)\mathcal{J}(Q,W) denote its Jacobian algebra. The algebra is called g\operatorname{g}-tame or EE-tame according to the corresponding tameness conditions.

Asai–Iyama's conjecture. If (Q,W)(Q,W) is a non-degenerate Jacobi-finite quiver with potential, then

J(Q,W) is g-tameJ(Q,W) is E-tame.\mathcal{J}(Q,W)\text{ is }\operatorname{g}\text{-tame}\quad\Longleftrightarrow\quad\mathcal{J}(Q,W)\text{ is }E\text{-tame}.

This conjecture was posed by Asai and Iyama for arbitrary finite-dimensional algebras. The paper studies the equivalence in substantial classes of Jacobian algebras, but the stated general conjecture remains open.
