Upper bounds on the genus of hyperelliptic Albanese fibrations

Songbo Ling, Xin LÃ¼

Let $S$ be a minimal irregular surface of general type, whose Albanese map induces a hyperelliptic fibration $f : S \to B$ of genus $g$ .We prove a quadratic upper bound on the genu…

Albanese fibrations of surfaces with low slope

Songbo Ling, Xin LÃ¼

Let $S$ be a minimal irregular surface of general type, whose Albanese map induces a fibration $f : S \to C$ of genus $g$ .We prove a linear upper bound on the genus $g$ if $K_S^2\l…
