Algebraic capacities as tropical polynomials over the reduced -positive symplectic cone
Tian-Jun Li, Shengzhen Ning
In a series of work [Wor22], [Wor21] and [CW20], algebraic capacities were introduced in an algebraic manner for polarized algebraic surfaces and applied to the symplectic embeddin…

Almost toric presentations of symplectic log Calabi-Yau pairs
Tian-Jun Li, Jie Min, Shengzhen Ning
It is known that the union of fibers over elliptic singularities of an almost toric fibered (ATF) closed symplectic four-manifold forms a symplectic log Calabi-Yau (LCY) divisor. I…
