The Classical r-matrix of AdS/CFT and its Lie Bialgebra Structure
نویسنده
چکیده
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, which leads to a quasitriangular Lie bialgebra as the underlying symmetry algebra. On the fundamental representation our r-matrix coincides with the classical limit of the quantum R-matrix.

A Secret Symmetry of the AdS/CFT S-matrix
We find a new quantum Yangian symmetry of the AdS/CFT S-matrix, which complements the original su(2|2) symmetry to gl(2|2) and does not have a Lie algebra analog. Our finding is motivated by the Yangian double structure discovered at the classical level. [email protected] [email protected] [email protected]
متن کاملA Yangian Double for the AdS/CFT Classical r-matrix
We express the classical r-matrix of AdS/CFT in terms of tensor products involving an infinite family of generators, which takes a form suggestive of the universal expression obtained from a Yangian double. This should provide an insight into the structure of the infinite dimensional symmetry algebra underlying the integrability of the model, and give a clue to the construction of its universal...
متن کاملQuantum E(2) Groups and Lie Bialgebra Structures
Lie bialgebra structures on e(2) are classified. For two Lie bialgebra structures which are not coboundaries (i.e. which are not determined by a classical r-matrix) we solve the cocycle condition, find the Lie-Poisson brackets and obtain quantum group relations. There is one to one correspondence between Lie bialgebra structures on e(2) and possible quantum deformations of U (e(2)) and E(2).

In this research we have studied the Brownian motion of a heavy particle in thermalized plasma. This plasma is made of quarks and gluons and it is different with normal plasma. Since, coupling constant is strong in this plasma, usual perturbation method does not work for the study of this plasma. For this purpose AdS/CFT duality is used. Based on the AdS/CFT duality to consider temperature...
متن کاملA New Lie Bialgebra Structure
We describe the Lie bialgebra structure on the Lie superalgebra sl(2, 1) related to an r−matrix that cannot be obtained by a Belavin-Drinfeld type construction. This structure makes sl(2, 1) into the Drinfeld double of a four-dimensional subalgebra. It is well-known that non-degenerate r−matrices (describing quasitriangular Lie bialgebra structures) on simple Lie algebras are classified by Bela...
