Abstract

FOR A MAGNETIZED PLASMA THE DYNAMIC PROBLEMS OF LARGE LARMOR RADIUS (LLR) EFFECTS ARE CLASSIFIED WITH RESPECT TO THE TYPES OF ADOPTED INITIAL PERTURBATIONS. IN ADDITION, THE SPECIAL EXAMPLE OF LLR EFFECTS ON ELECTROSTATIC FLUID MOTION IS CONSIDERED IN MORE DETAIL. THE ANALYSIS OF SUCH A TYPE OF MOTION INCLUDES THE LIMITING CASES OF MHD BEHAVIOUR, AND OF A LARGE DEBYE DISTANCE LEADING TO FREE STREAMING. AN OUTLINE IS PRESENTED OF THE GENERAL SOLUTION INCLUDING THE FEEDBACK OF THE ELECTRIC FIELD PERTURBATION ON PARTICLE DYNAMICS. THE RESULTS OF THE PRESENT ANALYSIS INCLUDE A TIME DEPENDENCE OF THE MACROSCOPIC FIELD QUANTITIES WHICH CANNOT BE EXPRESSED IN THE SIMPLE FORM EXP(IWT), WHERE W IS A COMPLEX FREQUENCY WITH SCALAR REAL AND IMAGINARY PARTS. CONSEQUENTLY, LLR EFFECTS CANNOT BE TREATED ACCURATELY IN TERMS OF THIS SIMPLIFIED KINETIC APPROACH. INSTEAD THE INVERSE LAPLACE TRANSFORM CAN BE APPLIED, AND THE TIME DEPENDENCE BE TREATED IN TERMS OF THE LAPLACE OPERATOR.
