%0 Journal Article %T Reflection equation and twisted Yangians %A Andrey Mudrov %J Mathematics %D 2006 %I arXiv %R 10.1063/1.2762176 %X With any involutive anti-algebra and coalgebra automorphism of a quasitriangular bialgebra we associate a reflection equation algebra. A Hopf algebraic treatment of the reflection equation of this type and its universal solution is given. Applications to the twisted Yangians are considered. %U http://arxiv.org/abs/math/0612737v2
