Calabi-Yau Threefold Singularities and their Universal Quilts
Elizabeth Gasparim, Carlos Simpson, Bruno Suzuki +1
We introduce the notion of universal quilt for toric CY3 singularities and construct examples when the universal quilts are themselves smooth Calabi-Yau threefolds. Such quilts are…

Hyperelliptically fibred surfaces with nodes
Edoardo Ballico, Elizabeth Gasparim, Bruno Suzuki
Using elementary methods of algebraic geometry, we present constructions of hyperelliptically fibred surfaces containing nodal fibres.

Infinite dimensional families of Calabi-Yau threefolds and moduli of vector bundles
Edoardo Ballico, Elizabeth Gasparim, Bruno Suzuki
We study noncompact Calabi-Yau threefolds, their moduli spaces of vector bundles and deformation theory. We present Calabi-Yau threefolds that have infinitely many distinct deforma…
