On the construction problem for Hodge numbers

摘要

For any symmetric collection (h(p,q))(p+q=k) of natural numbers, we construct a smooth complex projective variety X whose weight-k Hodge structure has Hodge numbers h(p,q) (X) = h(p,q) ; if k = 2m is even, then we have to impose that h(m,m) is bigger than some quadratic bound in m. Combining these results for different weights, we solve the construction problem for the truncated Hodge diamond under two additional assumptions. Our results lead to a complete classification of all nontrivial dominations among Hodge numbers of Kahler manifolds.
