Symplectic replacement conjecture for friendly Calabi–Yau algebras

About 20 years old · traced to

Let (D,ω,ξ)(D,\omega,\xi) be the symplectic data used in the universal construction, and let AA be a friendly algebra satisfying the stated Calabi–Yau condition. Theorem main(ii) represents AA using homologically symplectic data (D,ω,ξ)(D,\omega,\xi). Symplectic replacement conjecture. In Theorem main(ii), one can replace “homologically symplectic” by “symplectic.” This would strengthen the universal construction by showing that the representing data can be chosen symplectic rather than only homologically symplectic. The source gives no resolution evidence.
