MODULI SPACE OF CALABI-YAU MANIFOLDS
Published 1991“…We present an accessible account of the local geometry of the parameter space of Calabi-Yau manifolds. It is shown that the parameter space decomposes, at least locally, into a product with the space of parameters of the complex structure as one factor and a complex extension of the parameter space of the Kähler class as the other. …”

On the Connectedness of the Moduli Space of Calabi--Yau Manifolds
Published 1995“…We show that the moduli space of all Calabi-Yau manifolds that can be realized as hypersurfaces described by a transverse polynomial in a four dimensional weighted projective space, is connected. …”

Calabi-Yau manifolds and SU(3) structure
Published 2019“…Among the wide range of possible SU(3) structures we find Strominger-Hull systems, suitable for heterotic or type II string compactifications, on all complete intersection Calabi-Yau manifolds. These SU(3) structures of Strominger-Hull type have a non-vanishing and non-closed three-form flux which needs to be supported by source terms in the associated Bianchi identity. …”

CALABI-YAU MANIFOLDS IN WEIGHTED P4
Published 1990“…It has recently been recognized that the relation between exactly solvable conformal field theory compactifications of the Heterotic String and Calabi-Yau manifolds necessarily involves the discussion of embeddings in weighted projective space. …”

New Calabi-Yau Manifolds with Small Hodge Numbers
Published 2008“…It is known that many Calabi-Yau manifolds form a connected web. The question of whether all Calabi-Yau manifolds form a single web depends on the degree of singularity that is permitted for the varieties that connect the distinct families of smooth manifolds. …”

Finite distance between distinct Calabi-Yau manifolds.
Published 1989“…Moduli spaces for a wide class of Calabi-Yau manifolds with different numerical invariants (and thus topologically distinct) can be assembled into a connected web in which all distances are finite. …”

A new construction of Calabi–Yau manifolds: Generalized CICYs
