Physical models of intermittency in fully developed turbulence employ many
phenomenological concepts such as active volume, region, eddy, energy
accumulation set, etc, used to describe non-uniformity of the energy cascade.
In this paper we give those notions a precise mathematical meaning in the
language of the Littlewood-Paley analysis. We further use our definitions to
recover scaling laws for the energy spectrum and second order structure
function with proper intermittency correction.Comment: This is an updated version. Published in SIMA, 201
