Exploring the M-theory effective action

Triangular Seminar Michael Green (DAMTP)

15:00 KCL
room 1B06

This talk will survey recently deduced features of the ten-dimensional effective action for four gravitons in type II string theories. Duality with M-theory together with supersymmetry leads to a number of nontrivial higher derivative four-graviton interactions whose non-perturbative structure is completely determined by a collection of Poisson equations on moduli space and is consistent with data provided by string perturbation theory.
