Abstract : Synchrotron and Cherenkov radiation below the plasma frequency from particles spiraling in a magnetoplasma have been investigated. Both the longitudinal and transverse emissivity were calculated for mildly relativistic particles with particular attention being given to radiation from resonance regions. A new and stronger inequality for the density dependence at fixed entropy of the equilibrium energy of an arbitrary collection of point particles interacting with Coulomb (inverse power law) forces has been derived. Calculations based upon this derivation are necessary for models of the heavy planets as well as for models of stellar structure. A dynamo mechanism for solar flare energy production at photospheric heights was investigated. A set of equations for the motions of ions and electrons located just above the photpsphere was obtained which facilitates the derivation of quantitative results. The problem of two-dimensional hydrodynamics with rotation, i.e., Rossby waves in a rotating disc of incompressible fluid, was examined. (Author)
