Abstract
Let be a smooth minimal complex projective surface of maximal Albanese dimension. Under the assumption that the canonical class of is ample and , we show thus improving the well-known Severi inequality .
We also give stronger inequalities under extra assumptions on the Albanese map or on the canonical map of .
