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. 

Twisted Yangians and symmetric pairs

We describe recent work on the twisted Yangians Y(g,h) which arise as boundary remnants of Yangians Y(g) in 1+1D integrable field theories, bringing out the special role played by the requirement

Twisted Yangians for symmetric pairs of types B, C, D

We study a class of quantized enveloping algebras, called twisted Yangians, associated with the symmetric pairs of types B, C, D in Cartan’s classification. These algebras can be regarded as coideal

Drinfeld J Presentation of Twisted Yangians

We present a quantization of a Lie coideal structure for twisted half-loop algebras of finite-dimensional simple complex Lie algebras. We obtain algebra closure relations of twisted Yangians in

Twisted Yangians, twisted quantum loop algebras and affine Hecke algebras of type BC

We study twisted Yangians of type AIII which have appeared in the literature under the name of reflection algebras. They admit q-versions which are new twisted quantum loop algebras. We explain how

Drinfel'd basis of twisted Yangians

We present a quantization of a Lie bi-ideal structure for twisted half-loop algebras of finite dimensional simple complex Lie algebras. We obtain Drinfel'd basis formalism and algebra closure

Reflection algebras for sl(2) and gl(1|1)

We present a generalization the G. Letzter's theory of quantum symmetric pairs of semisimple Lie algebras for the case of quantum affine algebras. We then study solutions of the reflection equation

From Twisted Quantum Loop Algebras to Twisted Yangians

We prove how the Yangian of glN in its RTT presentation and Olshanski's twisted Yangians for the orthogonal and symplectic Lie algebras can be obtained by a de- generation process from the

(Quantum) twisted Yangians: symmetry, Baxterisation and centralizers

Based on the (quantum) twisted Yangians, integrable systems with special boundary conditions, called soliton nonpreserving (SNP), may be constructed. In the present article we focus on the study of

Gauge theory and boundary integrability

A bstractWe study the mixed topological/holomorphic Chern-Simons theory of Costello, Witten and Yamazaki on an orbifold (Σ×ℂ)/ℤ2, obtaining a description of lattice integrable systems in the presence

Finite dimensional irreducible representations of twisted Yangians

We study quantized enveloping algebras called twisted Yangians. They are analogs of the Yangian Y(gl(N)) for the classical Lie algebras of B, C, and D series. The twisted Yangians are subalgebras in

REPRESENTATIONS OF REFLECTION ALGEBRAS

We study a class of algebras B(n,l) associated with integrable models with boundaries. These algebras can be identified with coideal subalgebras in the Yangian for gl(n). We construct an analog of

Fundamental representations of Yangians and singularities of R-matrices.

The construction of Ä-matrices is closely related to the representation theory of quantum groups. In particular, there is an important class of quantum groups, called Yangians, such that to every
