Papers I have written that relate to my current research interests in mirror
symmetry:
Picard Ranks of K3
Surfaces of BHK Type, to appear in the Fields Institute Monograph Series.
- Abstract: We give an explicit formula for the Picard ranks of
K3 surfaces that have Berglund-Hübsch-Krawitz (BHK) Mirrors over an algebraically
closed field. These K3 surfaces are those that are certain orbifold quotients of
weighted Delsarte surfaces. The proof is an updated classical approach of Shioda
using rational maps to relate the transcendental lattice of a Fermat hypersurface
of higher degree to that of the K3 surfaces in question. The end result shows that
the Picard ranks of a K3 surface of BHK-type and its BHK mirror are intrinsically
intertwined. We end with an example of BHK mirror surfaces that, over certain
fields, are supersingular.
BHK Mirrors via Shioda
Maps, Advances in Theoretical and Mathematical Physics, 17 no. 6 (2013), 1425-1449.
- Abstract: In this paper, we give an elementary
approach to proving the birationality of multiple
Berglund-Hübsch-Krawitz (BHK) mirrors by using Shioda maps. We
do this by creating a birational picture of the BHK
correspondence in general. Although a similar result has been
obtained in recent months by Shoemaker, our proof is new in that
it sidesteps using toric geometry and drops an unnecessary
hypothesis. We give an explicit quotient of a Fermat variety to
which the mirrors are birational.

Mirror Quintics,
discrete symmetries and Shioda Maps (with Gilberto Bini and
Bert van Geemen) Journal of Algebraic Geometry, 21 (2012), 401-412.
- Abstract: In a recent paper, Doran, Greene
and Judes considered one parameter families of quintic
threefolds with finite symmetry groups. A surprising result was
that each of these six families has the same Picard Fuchs
equation associated to the holomorphic 3-form. In this paper we
give an easy argument, involving the family of Mirror Quintics,
which implies this result. Using a construction due to Shioda,
we also relate certain quotients of these one parameter families
to the family of Mirror Quintics. Our constructions generalize
to degree n Calabi Yau varieties in (n-1)-dimensional projective
space.
