Some previously obtained physical solutions [1–3] of Yang’s equations forSU(2) gauge fields , Charap’s equations for pion dynamics [5,6] and their combination as proposed by Chakraborty and Chanda  have been presented. They represent different physical characteristics, e.g. spreading wave with solitary profile which tends to zero as time tends to infinity, spreading wave packets, solitary wave with oscillatory profile, localised wave with solitary profile which becomes plane wave periodically, and, wave packets which are oscillatory in nature.
