R-matrices of three-state Hamiltonians solvable by Coordinate Bethe Ansatz
T. Fonseca, L. Frappat, E. Ragoucy
We review some of the strategies that can be implemented to infer an -matrix from the knowledge of its Hamiltonian. We apply them to the classification achieved in arXiv:1306.63…

Finite Dimensional KP τ-functions I. Finite Grassmannians
F. Balogh, T. Fonseca, J. Harnad
We study τ-functions of the KP hierarchy in terms of abelian group actions on finite dimensional Grassmannians, viewed as subquotients of the Hilbert space Grassmannians of Sato, S…
