HIGHLIGHTS
- What: The authors investigate more precisely the cotangent bundle 1S of a smooth projective surface S and show that such a sheaf can be either L-concave or not with respect to a big and semiample line bundle L The authors apply Theorem 1.3 to a general H -surface S and L D OS.C /, with C a general H -curve contained in S. Using the fact that the contracted divisor is exactly E D 1 S, the authors show that 1S is L-liftable and H 0.1S / D 0.
