Unobstructed deformations for singular Calabi-Yau varieties

Robert Friedman

Let $Y$ be a compact Gorenstein analytic space with only isolated singularities and trivial dualizing sheaf. A recent paper of Imagi studies the deformation theory of $Y$ in case t…

Limiting mixed Hodge structures associated to I-surfaces with simple elliptic singularities

Robert Friedman, Phillip Griffiths

An I-surface $X$ is a surface of general type with $K_{X}^{2} = 1$ and $p_{g} (X) = 2$ . This paper studies the asymptotic behavior of the period map for I-surfaces acquiring simple elliptic…
