Abstract
A general link between geometry and intermittency in passive scalar turbule nce is established. The anomalous part of the scalar correlation functions is shown to be dominated by special functions of particle configurations. T heir major property is that those functions calculated along the particle t rajectories remain statistically constant in time. Those conservation laws qualitatively imply the persistence of scalar particles in strongly cluster ed geometries.
