Upper bounds on the genus of hyperelliptic Albanese fibrations

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 genus g (i.e., $g\leq h\big (\chi (\mathcal {O}_S)\big )$ , where h is a quadratic function). We also construct ex...
