Resumen de On the analytic capacity and curvature of some Cantor sets with non-$\sigma$-finite length

Pertti Mattila

• We show that if a Cantor set $E$ as considered by Garnett in \cite{G2} has positive Hausdorff $h$-measure for a non-decreasing function $h$ satisfying $\int^1_0r^{-3}\,h(r)^2\,dr<\infty$, then the analytic capacity of $E$ is positive. Our tool will be the Menger three-point curvature and Melnikov's identity relating it to the Cauchy kernel. We shall also prove some related more general results.
