Nongeometric heterotic strings and dual F-theory with enhanced gauge groups
Yusuke Kimura
Eight-dimensional nongeometric heterotic strings were constructed as duals of F-theory on lattice polarized K3 surfaces by Malmendier and Morrison. We…
in F-theory on K3 surfaces without section as double covers of Halphen surfaces
Yusuke Kimura
We investigate F-theory models with a discrete gauge symmetry and gauge symmetries. We utilize a class of rational elliptic surfaces lacking a global section…
F-theory models on K3 surfaces with various Mordell-Weil ranks -constructions that use quadratic base change of rational elliptic surfaces
Yusuke Kimura
We constructed several families of elliptic K3 surfaces with Mordell-Weil groups of ranks from 1 to 4. We studied F-theory compactifications on these elliptic K3 surfaces times a K…
K3 surfaces without section as double covers of Halphen surfaces, and F-theory compactifications
Yusuke Kimura
We construct several examples of genus-one fibered K3 surfaces without a global section with type fibers, by considering double covers of a special class of rational ellipt…
