In a joint work with Alexander Lubotzky and Ron Rosenthal, we prove the existence of bounded degree coboundary expanders. Our work makes use of Keevash’s construction: We show that the union of a constant number of designs constructed according to Keevash’s random construction is with high probability a good coboundary expander.
Joint work with A. Grzesik, T. Klimošová, D. Král’, and J. Volec.
