Reflection algebras for SL(2) and GL(1|1) [PDF]
Vidas RegelskisWe study solutions of the reflection equation for the quantum affine algebras U_q(sl(2)) and U_q(gl(1|1)) and their Yangian limit for singlet (diagonal) and vector (non-diagonal) boundary conditions. We construct the corresponding quantum affine coideal subalgebras that are based on the quantum symmetric pairs, and the (generalized) twisted Yangians.View original: http://arxiv.org/abs/1206.6498
