Abstract

we discuss a framework for constructing large subsets of \(\mathbb{R}^n\) and \(K^n\) for non-archimedean local fields \(K\). This framework is applied to obtain new estimates for the Hausdorff dimension of angle-avoiding sets and to provide a counterexample to a limiting version of the Capset problem.
