Title: On the stability of solitary kinetic Alfvén waves
Abstract: The stability of the solitary kinetic Alfvén wave is investigated.In the one-dimensional fully nonlinear case the wave is shown to be stable against perturbations in the amplitudes.Solitary Alfv~n waves have been employed in the transverse to B 0, description of large amplitude magnetic structuresin = (_eIm.~~)(a2~Iaxat)space-and astro-physics.In an isotropic plasma it is 1X 1 1well known that such localized waves are subject to a Scaling the transverse coordinate to p5 = (Te/mi)~2
