Ching Hung Lam (Academia Sinica)「Vertex operator algebras, lattices and their automorphism groups」

In these three lectures, I will discuss the relations between vertex operator algebras and several combinatorial objects such as integral lattices and binary codes. In particular, I will explain how to use the theory of lattices and binary codes to study the structures of certain VOAs and their automorphism groups.

Lecture 1: Lattice VOA and Virasoro VOA. (1/19)

Lecture 2: Miyamoto involutions and Framed VOA (1/20)

Lecture 3. $EE_8$-lattices and VOAs generated by Ising vectors (1/21)
