Off-shell symmetry algebra of the AdS4 x CP3 superstring
Abstract
By direct calculation in classical theory we derive the central extension of the off-shell symmetry algebra for the string propagating in AdS4 x CP3. It turns out to be the same as in the case of the AdS5 x S5 string. We also elaborate on the kappa-symmetry gauge and explain, how it can be chosen in a way which does not break bosonic symmetries.
