Abstract:
Counting the graded dimensions of the vacuum spaces of various modules of affine Lie algebras in two different ways give interesting partition identities. For example, the famous Roger-Ramanujan identities can be proved using representations of the affine Lie algebra A_1^{(1)} (ref [LW]). Representation of other affine Lie algebras has been used to prove Roger-Ramanujan type identities in the works of Bos, Misra, Mandia. Capparelli proved certain partition identities using representations of A_2^{(2)} upto level 3.
In this talk, I will present evidence for new (conjectured) partition identities using level 4 modules (level (4,0), and (2,1)) of A_2^{(2)}. For level (4,0), this identity states that the number of partitions of n using parts congruent to 2, 3, 4, 10, 11, 12 modulo 14 is the same as the number of partitions of n with parts greater than one, and with certain type of sub-partitions forbidden (e.g., two consecutive numbers cannot be parts, a part cannot repeat thrice, etc.).
