Abstract
Covariant quantization of self-dual strings in 2 + 2 flat dimensions reduces them to their zero modes, a consequence of extended world-sheet supersymmetry. We demonstrate how to arrive at the same result more directly by employing a “double” light-cone gauge. An unconventional feature of this gauge is the removal of anticommuting degrees of freedom by commuting symmetries and vice versa. The reducibility of the N = 4 string and its equivalence with the N = 2 string become apparent.
