A harmonic or stationary measure is said to be Regular if it is Absolutely Continuous with respect to Lebesgue Measure and Singular if it is not. I need to understand the Regularity and Singularity of Harmonic and Stationary Measures. Despite saying that, I actually know nothing about these types of measures. Therefore, I am looking for highly recommended references on these concepts (to be more precise, to be able first to understand the concepts of harmonic and stationary measures and then the regularity and singularity of these kinds of measures). Thanks in advance.
