报告摘要：

We give a complete classification and characterization of OZ-type vertex operator algebras generated by Ising vector of $\sigma$-type. Furthermore we prove that all these vertex operator algebras are rational, $C_2$-cofinite and unitary, with which we prove that the classification theorem of 3-transposition groups $G_{\frac{1}{2},\frac{1}{2}}$ realizable by vertex operator algebras, given by Matuo, still holds without the positivity assumption. This is a joint work with Ching-Hung Lam and Hiroshi Yamauchi.
