Abstract: Starting from this week we plan to spend three weeks to discuss Chapter 4 of the book `Elementary Number Theory, Group Theory, and Ramanujan Graphs' (G. Davidoff, P. Sarnak and A. Valette, Cambridge University Press, 2003). In this presentation we will give constructions of the family of Ramanujan graphs $X^{p, q}$ and discuss their girth and connectedness.
