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…
Hadamard products and BPS networks
Mohamed Elmi
We study examples of fourth-order Picard-Fuchs operators that are Hadamard products of two second-order Picard-Fuchs operators. Each second-order Picard-Fuchs operator is associate…
Time reversal and invariance in Calabi-Yau compactifications
Kilian Bönisch, Mohamed Elmi, Amir-Kian Kashani-Poor +1
We revisit the question of time reversal and invariance in Calabi-Yau compactifications. We show that time reversal invariance is respected by quantum corrections to the prepo…
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…
