Weakly coupled N=4 Super Yang-Mills and N=6 Chern-Simons theories from u(2|2) Yangian symmetry
Fabian Spill
In this paper we derive the universal R-matrix for the Yangian Y(u(2|2)), which is an abstract algebraic object leading to rational solutions of the Yang-Baxter equation on represe…

The Classical r-matrix of AdS/CFT and its Lie Bialgebra Structure
N. Beisert, F. Spill
In this paper we investigate the algebraic structure of AdS/CFT in the strong-coupling limit. We propose an expression for the classical r-matrix with (deformed) u(2|2) symmetry, w…

On the Hopf algebra structure of the AdS/CFT S-matrix
Jan Plefka, Fabian Spill, Alessandro Torrielli
We formulate the Hopf algebra underlying the su(2|2) worldsheet S-matrix of the AdS_5 x S^5 string in the AdS/CFT correspondence. For this we extend the previous construction in th…
