STRUCTURE AND CLASSIFICATION OF SOME INTEGRABLE A_2^((2))-MODULES NOT BELONGING TO THE CATEGORY O

摘要

For the generalized Cartan matrix ■ of rank 2, we get a corresponding Kac-Moody algebra called twisted affine Lie algebra A2（2）. Let e0,e1, f0,f1, α0Ⅴ, α1Ⅴ be its Chevalley generators, then h = Cα0Ⅴ, ⊕Cα1Ⅴ⊕C is its Cartan subalgebra,
