The first relation implies a symmetry of the multifractal spectrum linking the multifractal exponents with indices $q<1/2$ to those with $q>1/2$. The second relation connects the wave function multifractality to that of Wigner delay times in a system with a lead attached.4 pages, 3 figuresMesoscale and Nanoscale PhysicsDisordered Systems and Neural Networkstext
