T-duality and world-sheet supersymmetry
Four-dimensional string backgrounds with local realizations of N = 4 world-sheet supersymmetry have, in the presence of a rotational Killing symmetry, only one complex structure which is an SO(2) singlet while the other two form an SO(2) doublet. Although N = 2 world-sheet supersymmetry is always pr...
