Classification of surfaces with the bounded cohomology property
Classify all smooth projective surfaces that satisfy the bounded cohomology property, namely, those for which there exists a constant c_X>0 such that h^1(O_X(C)) is at most c_X h^0(O_X(C)) for every curve C on X.

In general, it is an open problem to classify smooth projective surfaces with the BCP as posted by Ciliberto et al.Question 6.
