Abstract
We examine MHD Burgerlence using instanton path integral techniques. It is shown that the characteristic directions are of fundamental importance in t he extended functional space as well as the original physical space. For fo rced Burgerlence, statistical stationarity forces the system to adopt these characteristic directions. This nonperturbative result suggests that the a ttractor for MHD Burgerlence is a state of energy equidissipation, rather t han equipartition, supporting the: main conclusions from a perturbative, re normalization group analysis.
