The local dimension of a measure is a way to quantify its local behaviour. For self-similar measures that satisfy a suitable separation condition, it is well known that the set of attainable local dimensions is a closed interval, but for measures which fail to satisfy this condition the situation is more complicated and less well-understood. We will show that for a large class of self-similar measures on R with ‘controlled’ overlap the set of local dimensions is a finite union of (possibly singleton) compact intervals, the number of which is bounded by geometric properties of the underlying IFS.
