Vg. Kac et A. Rudakov, Representations of the exceptional Lie superalgebra E(3,6) II: Four seriesof degenerate modules, COMM MATH P, 222(3), 2001, pp. 611-661
Four Z(+)-bigraded complexes with the action of the exceptional infinite-di
mensional Lie superalgebra E(3,6) are constructed. We show that all the ima
ges and cokernels and all but three kernels of the differentials are irredu
cible E (3,6)-modules. This is based on the list of singular vectors and th
e calculation of homology of these complexes. As a result, we obtain an exp
licit construction of all degenerate irreducible E(3,6)-modules and compute
their characters and sizes. Since the group of symmetries of the Standard
Model SU(3) x SU(2) x U(1) (divided by a central subgroup of order six) is
a maximal compact subgroup of the group of automorphisms of E(3,6), our res
ults may have applications to particle physics.
