In this talk\, I will discuss how supersymmetry can also be made mani fest in a superspace ExFT. In this approach\, the fermionic coordinates ar e unified with the external spacetime coordinates\, which together are act ed on by external superdiffeomorphisms. The internal space and its section condition remain purely bosonic. This corresponds to the simplest way one might construct an exceptional superspace\, but even this proves surprisi ng: it cannot be done directly with the original supersymmetric formulatio ns of ExFT\, and one must instead relax or reformulate certain features (s uch as the vielbein postulates). I will sketch how this works for the case of E_7. The superspace Bianchi identities then lead to the explicit form of the on-shell p-form curvatures as well as their duality relations. Vari ous applications will also be discussed.\n LOCATION:https://researchseminars.org/talk/EGSS/12/ END:VEVENT END:VCALENDAR
