### Table 2 Finite-dimensional modules for Lie algebras of vector fields

1994

"... In PAGE 10: ... OLVER systems than Lie.) Table2 describes the di erent nite-dimensional modules for each of these Lie algebras. The rst column tells whether the module is necessarily spanned by monomials, i.... In PAGE 10: ... Finally, Table 4 describes the quantization condition resulting from the quasi- exactly solvability assumption that, assuming M = f1g, the Lie algebra admit a nite-dimensional module N. If the cohomol- ogy is trivial, so g is spanned by vector elds and the constant functions, then it automatically satis es the quasi-exactly solvable condition, with the associated nite-dimensional modules being explicitly described in Table2 . The maximal al- gebras, namely Case 11, sl(2) sl(2), Case 15, sl(3), and Case 24, gl(2) n Rr, play an important role in Turbiner apos;s theory of di erential equations in two dimensions with orthogonal polynomial solutions, [33].... ..."

### Table 4 Additional Primitive Lie Algebras of Vector Fields in R2

1996

"... In PAGE 3: ... For instance, extensive symbolic algebra calculations using the realization of so(3; R) given by Case 4.2 in Table4 failed to yield any real-valued potentials, even after allowing for a possible rescaling of the wave function by a non-zero gauge factor, cf. (7).... In PAGE 15: ... However, the complexi cation (or analytic continuation) of each of these ve additional Lie algebras will, of course, be equivalent, under a complex di eomorphism, to one of the complex normal forms on our list. The complete list of these additional real forms along with their canonical complexi- cations appears in Table4 ; the required changes of variables needed to change them into the canonical form appears later in this section. Therefore, to complete the classi cation of all real Lie algebras of rst-order di erential operators, we need only determine the real cohomology spaces associated with these ve additional real forms, and, further, to determine what values of the cohomology parameters will produce quasi-exactly solvable algebras.... In PAGE 21: ... Theorem 11. Every nite-dimensional Lie algebra of rst order di erential opera- tors with vector eld part given by one of the ve additional primitive real forms listed in Table4 is a subalgebra of one of the pseudo-orthogonal Lie algebras given by (45). 6.... ..."
