Martin B. Einhorn
TL;DR
This paper explores the SL(2,R) symmetry in Type IIB supergravity, focusing on how it appears in Euclidean signature solutions and contrasting it with Lorentzian cases.
Contribution
It clarifies the manifestation of SL(2,R) symmetry in dual formulations of Type IIB supergravity under different spacetime signatures.
Findings
SL(2,R) symmetry is evident in Euclidean solutions
Differences between Lorentzian and Euclidean signatures are analyzed
Dual formulations reveal symmetry properties in supergravity
Abstract
We discuss the relation between the dual formulations of Type IIB supergravity emphasizing the differences between Lorentz and Euclidean signature. We demonstrate how the SL(2,R) symmetry of the usual action is manifested in the solution of the equations of motion with Euclidean signature for the dual theory.
