OGG - Operators, Graphs, Groups

 Expander graphs have been a topic of central importance in CS in the last six decades, with applications also in pure math in the last 30 years.  In the last 15 years, a theory of high-dimensional expanders (HDX)  has emerged, again, with applications in pure math and CS.  We will illustrate it by several examples, stressing the difference between the high-dimensional theory and the one-dimensional graph theory.
