    "abstract": "Recently, Gomez-Ullate et al. (1) have studied a particular N-particle\nquantum problem with an elliptic function potential supplemented by an external\nfield. They have shown that the Hamiltonian operator preserves a finite\ndimensional space of functions and as such is quasi exactly solvable (QES). In\nthis paper we show that other types of invariant function spaces exist, which\nare in close relation to the algebraic properties of the elliptic functions.\nAccordingly, series of new algebraic eigenfunctions can be constructed.",
