Hyperelliptic surfaces of general type with \(K^ 2<4\chi\)
The author is concerned with hyperelliptic surfaces S of general type with \(K^ 2<4\chi -28\); then the image of the Albanese map of S is a curve. As a corollary, an extension of a theorem of Horikawa on the existence of hyperelliptic pencils is obtained.
