Puzzles in Eulerian and Lagrangian turbulence — •Rainer Grauer — Institut für Theor. Physik I, Ruhr-Universität Bochum

Basic and elementary questions which arise in the context of fully developed turbulent systems are still open and discussed controversially. Some of these questions are:

- What is the relation between Eulerian longitudinal and transversal structure functions?

- Is there a relation between Eulerian and Lagrangian fluctuations?

- Can we say something about the energy spectrum in slightly more complex systems as e.g. in magnetohydrodynamical turbulence?

In my talk, I will present different viewpoints and possible solution strategies.
