“…Possible applications in the spectral theory of self-adjoint operators serve as an additional stimulus for a further investigation of singularly continuous measures [6]. For example, one can note the following researches of singular measures: singularity of Hewitt-Stromberg measures on Bedford-McMullen carpets [2], the mutual singularity of certain measures (see [6,8,24,46,47] and references therein), dimensions of measures [13,20,23].…”
