KA2W03 - Mathematical physics: algebraic cycles, strings and amplitudes Using a natural combinatorial generalization of the Fermat quartic and the Batyrev mirror symmetry construction, we obtain a collection of K3 surface pencils of generic Picard rank 19 in Gorenstein Fano toric varieties. We characterize point counts on these varieties over finite fields using Picard-Fuchs equations and classical hypergeometric functions.
