Abstract
The Davey-Stewartson equations are derived in a plasma system by the r eductive perturbation method. Modulational instability of a plane wave is discussed including a finite ion temperature effect. Certain parti cular solutions of the equations are also obtained by means of a Linea rization technique. One of them shows the ''reconnection'' of solitons . We show that this reconnection solution corresponds to the resonant type of usual soliton solutions.
