Selected topics in string field theory
Georg Stettinger
This thesis contains of two parts: The first part is a pedagogical introduction into the field of bosonic SFT. After discussing some general properties we expect, Witten's open SFT…

A boundary term for open string field theory
Georg Stettinger
We consider Witten's open string field theory in the presence of a non-trivial boundary of spacetime. For the kinetic term, we derive a Gibbons-Hawking-type contribution that has t…

Sliver frame stubs in OSFT via auxiliary fields
Georg Stettinger
In this short paper we want to generalize some recent concepts related to stubs in open string field theory. First, we modify the auxiliary field method by Erbin and Firat [#Erbin2…
