Enlarged exceptional symmetries of first-quantized F-theory

TL;DR

This paper reveals that the Lagrangian formalism of F-theory exhibits larger exceptional symmetries than previously known from supergravity, demonstrated through the D=5 case, simplifying the understanding of its symmetry structure.

Contribution

It uncovers larger exceptional symmetries in the Lagrangian formalism of F-theory, extending prior results from Hamiltonian formulations.

Findings

Larger exceptional symmetries identified in F-theory Lagrangian formalism

Simplification of symmetry derivation for D=5 case

Extension of supergravity symmetry results to F-theory

Abstract

The exceptional symmetries of supergravity have been reproduced from the Hamiltonian formulation of the classical mechanics of F-theory. We now find the Lagrangian formalism has even larger exceptional symmetries, simplifying its derivation: We discuss D = 5 as an example.
