Title: Equitable partitions and quotient graphs
Abstract: In this talk I will present the recent preprint myself and Fred Cançado have put on arXiv https://arxiv.org/pdf/2411.09157
I will essentially survey known results that present equivalent condititions for graphs to admit similar quotients according to equitable partitions. Then I will introduce the concept of a symmetrized quotient, and finally present our main result. The talk should be accessible to anyone with basic linear algebra and combinatorics background.
