【 摘 要 】

We give a formula for Hodge numbers of double coverings with h(2,0) = 0 over compact Kahler manifolds. As an application, we consider Calabi-Yau double coverings and calculate their Hodge numbers. In this way, we find several pairs (h(1,1), h(1,2)) of Hodge numbers of Calabi-Yau threefolds that do not come from toric setting. (C) 2018 Elsevier B.V. All rights reserved.
