We also construct restricted Lie 2-algebras from A(m)-algebras, restricted Leibniz algebras, restricted right-symmetric algebras. Finally, we prove that there is a one-to-one correspondence between strict restricted Lie 2-algebras and crossed modules of restricted Lie algebras.展开更多

It turns out that the representation theory of H4 is quite different from the theory of representations of Heisenberg algebras. We also study the extension of the vertex operator algebra VH4 (e, 0) by the even lattice L. We give the structure of the extension VH4 (e, 0) [L] and its irreducible modules via irreducible representations of VH4(e, 0) viewed as a vertex algebra.展开更多
