New discretised polynomial expander and incidence estimates
Open access0 citations
Abstract
Abstract We present two applications of recent developments in incidence geometry. One is a ‐discretised version of a particular ‘Elekes–Rónyai’ expander problem. The second is an incidence estimate addressing the scenario in which both tubes, squares and their shadings satisfy non‐concentration assumptions.
