Bits and Pieces in Logarithmic Conformal Field Theory
Michael Flohr
These are notes of my lectures held at the first School & Workshop on Logarithmic Conformal Field Theory and its Applications, September 2001 in Tehran, Iran. These notes cover onl…
D-Brane Scattering of N=2 Strings
K. Juenemann, Bernd Spendig
The amplitudes for emission and scattering of N=2 strings off D-branes are calculated. We consider in detail the amplitudes <cc> and <occ> for the different types of D-branes. For…
Operator Product Expansion in Logarithmic Conformal Field Theory
Michael Flohr
In logarithmic conformal field theory, primary fields come together with logarithmic partner fields on which the stress-energy tensor acts non-diagonally. Exploiting this fact and…
Noncommutative Multi-Solitons in 2+1 Dimensions
Olaf Lechtenfeld, Alexander D. Popov
The study of noncommutative solitons is greatly facilitated if the field equations are integrable, i.e. result from a linear system. For the example of a modified but integrable U(…
A Heterotic N=2 String with Space-Time Supersymmetry
Stefano Bellucci, Anton Galajinsky, Olaf Lechtenfeld
We reconsider the issue of embedding space-time fermions into the four-dimensional N=2 world-sheet supersymmetric string. A new heterotic theory is constructed, taking the right-mo…
