Degree Counting Theorems for 2x2 non-symmetric singular Liouville Systems

Yi Gu

Let $(M, g)$ be a compact Riemann surface with no boundary and $u = (u_{1}, u_{2})$ be a solution of the following singular Liouville system: $$Δ_g u_i+\sum_{j=1}^2 a_{ij}ρ_j(\frac{h_je^{u…

Surface fibrations with large equivariant automorphism group

Yi Gu

For a relatively minimal surface fibration $f : X \to C$ , the equivariant automorphism group of $f$ is, roughly speaking, the group of automorphisms of $X$ preserving the fibration s…

Counterexamples to Fujita's conjecture on surfaces in positive characteristic

Yi Gu, Lei Zhang, Yongming Zhang

We present counterexamples to Fujita's conjecture in positive characteristics. Precisely, we show that over any algebraically closed field $k$ of characteristic $p > 0$ and for any p…
