Abstract
An iterative filtering scheme is used for deriving the evolution of la rge scales in a plasma. The information lost by filtering out the smal l-scale fluctuations is accounted for by the introduction of an effect ive propagator and vertex operators in the Vlasov equation. These reno rmalizing terms correspond to large-scale diffusive effects. A general expression for the fluxes of energy and particles is obtained. The tr ansport coefficients are explicitly derived for the quasilinear limit and the guiding center approximation.
