The spaces of Kähler and holomorphically tamed symplectic forms on closed 4-manifolds
Tian-Jun Li, Shengzhen Ning
This paper investigates the uniqueness, connectedness and openness properties of spaces of Kähler forms on closed -manifolds, extending discussions in \cite{Li08,Sal13}. Motiva…
Symplectic log Kodaira dimension , affine-ruledness and unicuspidal rational curves
Tian-Jun Li, Shengzhen Ning
Given a closed symplectic -manifold , a collection of embedded symplectic submanifolds satisfying certain normal crossing conditions is called a symplectic divisor.…
Symplectic log Kodaira dimension , Hirzebruch--Jung strings and weighted projective planes
Tian-Jun Li, Shengzhen Ning
We study symplectic minimal resolutions of weighted projective planes from the perspective of disconnected symplectic divisors with symplectic log Kodaira dime…
Symplectic Classes on Elliptic Surfaces with positive Euler Number
Josef G. Dorfmeister, Tian-Jun Li
A key question for -manifolds admitting symplectic structures is to determine which cohomology classes admit a symplectic representative. The collec…
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…
