Abstract:We present two applications of recent developments in incidence geometry. One is a $\delta$-discretised version of a particular `Elekes--Rónyai' expander problem. The second application is an incidence estimate addressing the scenario when both tubes, squares and their shadings satisfy non-concentration assumptions.
