Protentials with logarithmic singularities occur in many situations. They are natural in systems with a zero or a pole of the derivative. They also occur in some number theoretical problems or in the study of diffraction measures of substitutions. In this talk I will give a survey of the recent development as well as some open problems. Most of the talk is based on joint work with A. Fan, W. Shen; Ph. Gohlke and G. Lamprinakis.
