Abstract
The nonlinear dynamical equation for the propagation of kinetic Alfvén waves has been derived in two dimensions using the two-fluid model of the plasma and by taking the adiabatic response for the background density in the presence of nonlinear electron heating and the ponderomotive force. Dynamically evolving filamentary structures are predicted. The effect of these filaments on solar wind turbulence and coronal heating has also been pointed out.
