報告摘要:In this talk, I will introduce a new result on a class of symmetric 2-designs which is regarded as a natural generalization of the projective planes in terms of parameters. Let $\mathcal D$ be a symmetric $2$-$(v,k,\lambda)$ designs, where $\lambda>1$ and the order $n=k-\lambda$ of $\mathcal D$ is a prime number. We show that if $G\leq Aut({\mathecal D})$ is flag-transitive then $G$ is point-primitive, and it is of affine or almost simple type. This is a joint work with Dr. Ziwei Lu.
