The Lebesgue measure of boundaries of multigeometric Cantorvals
Abstract
We prove that the boundary of every multigeometric Cantorval is a null set, and extend this result to a larger class of standard achievable Cantorvals. In addition, we discuss the sets of uniqueness of achievement sets and show that they always belong to the Borel class Gδ.
