On the bootstrap structure of Yangian-invariant factorized S-matrices
نویسنده
چکیده
We begin by taking the point of view of a physicist investigating the charge algebra of integrable field theories in 1+1 dimensions which have a Lie algebra valued, curvature-free, conserved current (of which notable examples are the principal chiral model and the GrossNeveu model and its generalizations). Such theories thus contain a charge Qa0, valued in a Lie algebra A, which acts additively on tensor products of asymptotically independent particle states: defining its action on a two-particle state to be ∆(Qa0), we have

The Full Set of C N -invariant Factorized S-matrices
We use the method of the tensor product graph to construct rational (Yangian invariant) solutions of the Yang-Baxter equation in fundamental representations of cn and thence the full set of cn-invariant factorized S-matrices.

متن کاملBulk and boundary g 2 factorized S - matrices
We investigate the g2-invariant bulk (1+1D, factorized) S-matrix constructed by Ogievetsky, using the bootstrap on the three-point coupling of the vector multiplet to constrain its CDD ambiguity. We then construct the corresponding boundary S-matrix, demonstrating it to be consistent with Y (g2, a1× a1) symmetry.
متن کاملSOLUTION-SET INVARIANT MATRICES AND VECTORS IN FUZZY RELATION INEQUALITIES BASED ON MAX-AGGREGATION FUNCTION COMPOSITION
Fuzzy relation inequalities based on max-F composition are discussed, where F is a binary aggregation on [0,1]. For a fixed fuzzy relation inequalities system $ A circ^{F}textbf{x}leqtextbf{b}$, we characterize all matrices $ A^{'} $ For which the solution set of the system $ A^{' } circ^{F}textbf{x}leqtextbf{b}$ is the same as the original solution set. Similarly, for a fixed matrix $ A $, the...
متن کاملBoundary scattering in the principal chiral model
In recent work on the (G×G-invariant) principal chiral model with boundary, we found that both classically integrable boundary conditions and quantum boundary S-matrices were classified by the symmetric spaces G/H. The connection is explained by the presence of a ‘twisted Yangian’ algebra of non-local charges.
متن کاملFactorization of the Effective Action in the IIB Matrix Model
We study the low-energy effective action of the IIB matrix model in the derivative interpretation, where the diffeomorphism invariance is manifest and arbitrary manifolds are described by matrices. We show that it is expressed as a sum of terms, each of which is factorized into a product of diffeomorphism invariant action functionals: S = ∑
