On the Datar-Mete-Song minimal slope conjecture

Xin Fu

We prove a conjecture of Datar-Mete-Song \cite{DMS} characterizing $J$ -slope semi-stability by the minimal $J$ -slope. More precisely, for a semi-stable pair of Kähler classes $(α,β…

The integral cohomology rings of four-dimensional toric orbifolds

Xin Fu, Tseleung So, Jongbaek Song

Let $X (P, I^»)$ be a 4-dimensional toric orbifold associated to a polygon $P$ and a characteristic function $I^»$ . Assuming that $X (P, I^»)$ is locally smooth over a vertex of $P$ , we d…
