Hasse-Witt invariants of Calabi-Yau varieties
Jin Cao, Mohamed Elmi, Hossein Movasati
We define the Hasse-Witt invariant of Calabi-Yau varieties in two different ways. The first method is through Cartier operator and the second method is through the theory of Calabi…

Some Identities For Periods of Hulek-Verrill Threefolds
Xenia de la Ossa, Mohamed Elmi
We study the Hulek--Verrill families of Calabi--Yau threefolds. They are birationally equivalent to fibred products of elliptic surfaces, so we expect to be able to compute periods…

A One Parameter Family of Calabi-Yau Manifolds with Attractor Points of Rank Two
Philip Candelas, Xenia de la Ossa, Mohamed Elmi +1
In the process of studying the zeta-function for one parameter families of Calabi-Yau manifolds we have been led to a manifold, first studied by Verrill, for which the quartic nume…
