Abstract:
By direct calculation in the classical theory, we derive the central extension of the off-shell symmetry algebra for a string propagating in AdS$_4\times\mathbb{CP}^3$. It turns out to be the same as in the case of the AdS$_5\times S^5$ string. We consider the choice of the $\kappa$-symmetry gauge in detail and also explain how this gauge can be chosen without breaking the bosonic symmetries.
