The R-matrix bootstrap

open access: yes, 2021
In this thesis, we extend the numerical S-matrix bootstrap program to 1+1d theories with a boundary, where we bootstrap the 1-to-1 reflection matrix (R-matrix). We review the constraints that a physical R-matrix must obey, namely unitarity, analyticiy and crossing symmetry.

WHAT IS A CLASSICAL R-MATRIX?

Functional Analysis and Its Applications, 1983
Classical r-matrices were introduced as a useful tool to deal with the Poisson bracket relations for classical integrable systems. They are a natural counterpart to R. Baxter's quantum matrices. Their study was initiated by the Leningrad group (L. S. Faddeev, E. Sklyanin et al.); important contributions are due to \textit{A. A.

Dual R-matrix integrability

Theoretical and Mathematical Physics, 2008
In this paper the authors propose another way, the so-called dual \(R\)-matrix integrability, to construct algebras of mutually commuting first integrals of some Euler-Arnold-type equations using the notion of the classical \(R\)-operator. Considered examples of the Lie algebras \(\mathfrak{g}\) with the Kostant-Adler-Symes and triangular ...
