Multiple points of dilation-stable Lévy processes
The Hausdorff dimension of the set of \(k\)-multiple points is computed for a symmetric Lévy process in \(\mathbb{R}^d\), \(d=2,3\), having independent self-similar components with similarity exponents \(\frac 12< H_j< 1\), \(1\leq j\leq d\). For the case of stable components see \textit{W. J. Hendricks} [Z. Wahrscheinlichkeitstheorie Verw. Geb. 28, 113-128 (1974; Zbl 0258.60028)].
