Abstract

We calculate the Assouad dimension of a planar self-affine set XX satisfying the strong separation condition and the projection condition and show that XX is minimal for the conformal Assouad dimension. Furthermore, we see that such a self-affine set XX adheres to very strong tangential regularity by showing that any two points of XX, which are generic with respect to a self-affine measure having simple Lyapunov spectrum, share the same collection of tangent sets.
