Negative Generators of the Virasoro Constraints for the BKP Hierarchy
Jingsong He, Kelei Tian, Angela Foerster
We give a straightforward derivation of the string equation and Virasoro constraints on the function of the BKP hierarchy by means of some special additional symmetry flows. Th…

Additional Symmetry of CKP hierarchy
Jingsong He, Kelei Tian, Angela Foerster +1
Based on the Orlov and Shulman's M operator, the additional symmetries and the string equation of the CKP hierarchy are established, and then the higher order constraints on …

Exact solvability in contemporary physics
A. Foerster, J. Links, H. -Q. Zhou
We review the theory for exactly solving quantum Hamiltonian systems through the algebraic Bethe ansatz. We also demonstrate how this theory applies to current studies in Bose-Eins…
