Systematic method to study the general structure of Bose-Einstein condensates with arbitrary spin

We develop a systematical method by which the investigation of the general structure of Bose-Einstein condensates with arbitrary spin has been reduced to solving a one-order linear partial-differential equation of a very simple form. Its general solutions for arbitrary spin are studied and a procedure is also developed to seek systematically the building blocks for constructing the general structure of Bose-Einstein condensates with arbitrary spin.
