Аннотация: For the real part of the Cauchy-type integral that is known to be the logarithmic potential of the double layer, a necessary and sufficient condition for the continuous extension to the Ahlfors-regular boundary is established. Sufficient conditions involving subclasses of Ahlfors-regular curves are also considered. Illustrative examples are presented.

Ключевые слова и фразы: logarithmic double layer potential, Cauchy-type integral, Ahlfors-regular curve, Král curve, Radon curve, Lyapunov curve.
