Some applications of the moduli space of -polarized K3 surfaces
Adrian Clingher, Andreas Malmendier, Brandon Williams
We study K3 surfaces polarized by the lattice through elliptic fibrations and orthogonal modular forms. Using an alternate genus-one fibration and its relative Ja…
Photon spheres, elliptic surfaces, and Seiberg-Witten geometry
Cordell Blankenship, Andreas Malmendier, Michael T. Schultz
We study null geodesics in Reissner-Nordström-de Sitter spacetime and in its Kiselev deformation through the elliptic curves defined by the radial equation. The relation o…

We construct non-geometric string compactifications by using the F-theory dual of the heterotic string compactified on a two-torus with two Wilson line parameters, together with a…
