String Field Theory Projectors for Fermions of Integral Weight
Matthias Ihl, Alexander Kling, Sebastian Uhlmann
The interaction vertex for a fermionic first order system of weights (1,0) such as the twisted bc-system, the fermionic part of N=2 string field theory and the auxiliary ηξsystem o…
Cyclicity of non-associative products on D-branes
M. Herbst, A. Kling, M. Kreuzer
The non-commutative geometry of deformation quantization appears in string theory through the effect of a B-field background on the dynamics of D-branes in the topological limit. F…
String Field Theory Vertices for Fermions of Integral Weight
Alexander Kling, Sebastian Uhlmann
We construct Witten-type string field theory vertices for a fermionic first order system with conformal weights (0,1) in the operator formulation using delta-function overlap condi…
Solving String Field Equations: New Uses for Old Tools
Alexander Kling, Olaf Lechtenfeld, Alexander D. Popov +1
It is argued that the (NS-sector) superstring field equations are integrable, i.e. their solutions are obtainable from linear equations. We adapt the 25-year-old solution-generatin…
