added publication data to:

- Yi-Zhi Huang,
*Vertex operator algebras, the Verlinde conjecture and modular tensor categories*, Proc. Nat. Acad. Sci.**102**(2005) 5352-5356 $[$arXiv:math/0412261, doi:10.1073/pnas.0409901102$]$

added pointer to today’s

- Yi-Zhi Huang,
*Representation theory of vertex operator algebras and orbifold conformal field theory*(arXiv:2004.01172)

I added two references at vertex operator algebra, in the bibliography section on deformations.

]]>added to the References at *vertex operator algebra* a pointer to their formalization as *factorization algebras of observables*.

I have expanded vertex operator algebra (more references, more items in the Properties-section) in partial support to a TP.SE answer that I posted here
