General boundary conditions for the sl(N) and sl(M|N) open spin chains

Résumé

Two types of boundary conditions ("soliton preserving" and "soliton non-preserving") are investigated for the sl(N) and sl(M|N) open spin chains. The appropriate reflection equations are formulated and the corresponding solutions are classified. The symmetry and the Bethe Ansatz equations are derived for each case. The connection between the "soliton non-preserving" boundary conditions and the twisted (super) Yangians is discussed.
