Sections, multisections, and U(1) fields in F-theory

© 2016, Journal of Singularities. All rights reserved. We show that genus-one fibrations lacking a global section fit naturally into the geometric moduli space of Weierstrass models. Elliptic fibrations with multiple sections (nonzero Mordell-Weil rank), which give rise in F-theory to abelian U(1) f...
