Dimension bounds for singular affine forms

Number Theory 2026-05-05 v4 Dynamical Systems

Abstract

In this paper, we establish upper bounds on the dimension of sets of singular-on-average and ω\omega-singular affine forms in singly metric settings, where either the matrix or the shift is fixed. These results partially address open questions posed by Das, Fishman, Simmons, and Urba\'nski, as well as Kleinbock and Wadleigh. Furthermore, we extend our results to the generalized weighted setup and derive bounds for the intersection of these sets with a wide class of fractals.
