# Rational K-matrices and representations of twisted Yangians

@article{Mackay2002RationalKA, title={Rational K-matrices and representations of twisted Yangians}, author={Niall J. Mackay}, journal={Journal of Physics A}, year={2002}, volume={35}, pages={7865-7876} }

We describe the twisted Yangians Y(g, h) which arise as boundary remnants of Yangians Y(g) in 1 + 1D integrable field theories. We describe and extend our recent construction of the intertwiners of their representations (the rational boundary S- or 'K'-matrices) and perform a case-by-case analysis for all pairs (g, h), giving the h-decomposition of Y(g, h)-representations where possible.
