Invertible Calabi-Yau Orbifolds over Finite Fields
Marco Aldi, Andrija Perunicic
In the context of Berglund-Huebsch mirror symmetry, we compute the eigenvalues of the Frobenius endomorphism acting on a p-adic version of Borisov's complex. As a result, we conjec…

Invertible Calabi-Yau Orbifolds over Finite Fields II
Marco Aldi, Andrija PeruniÄiÄ
We state a conjecture about the zeta function of crepant resolutions of Berglund--Hübsch orbifold hypersurfaces over a finite field. In addition to numerical evidence, we show tha…
