Desingularized fiber products of semi-stable elliptic surfaces with vanishing third Betti number
Published online by Cambridge University Press: 01 January 2009
Abstract
Desingularized fiber products of semi-stable elliptic surfaces with Hetale3=0 are classified. Such varieties may play a role in the study of supersingular threefolds, of the deformation theory of varieties with trivial canonical bundle, and of arithmetic degenerations of rigid Calabi–Yau threefolds.
