Reduced Solutions of Toda Systems for Arbitrary Complex Simple Lie Algebras

Yiqian Shi, Chunhui Wei, Bin Xu

We study reduced solutions of Toda systems generated by spherical metrics for an arbitrary complex simple Lie algebra. The main result is an intrinsic centralizer parametrization:…

Polynomial area growth for special Kähler metrics

Yiqian Shi, Ke Wang, Bin Xu

Let be an affine special Kähler metric on a punctured disc and let be its associated holomorphic cubic differential. We prove that if the -area of con…

Solution to SU(n+1) Toda system generated by spherical metrics

Yiqian Shi, Chunhui Wei, Bin Xu

Using the correspondence between solutions to the SU(n+1) Toda system on a Riemann surface and totally unramified unitary curves, we show that a spherical metric generates a fa…

Solutions to Toda system with cone singularities via toric curves on compact Riemann surfaces

Jingyu Mu, Yiqian Shi, Bin Xu

On a compact Riemann surface (X) with finite punctures (P_1, \ldots, P_k), we define toric curves as multi-valued, totally unramified holomorphic maps to (\mathbb{P}^n) with monodr…

The space of germs of extremal K\" ahler metrics in one dimension comprises three distinct components

Qing Chen, Yiqian Shi, Bin Xu

In the 1980s, Eugenio Calabi introduced the concept of {\it extremal K\" ahler metrics} as critical points of the -norm functional of scalar curvature in the space of K\" ahle…
