A generalization of the Lax pair for the pure spinor superstring in AdS5 x S5
arXiv:1303.2090
Abstract
We show that the Lax pair of the pure spinor superstring in AdS5xS5 admits a generalization where the generators of the superconformal algebra are replaced by the generators of some infinite-dimensional Lie superalgebra.
