Hirota bilinear method

 

 

 

 

Advantages of the bilinear formalism:

• Multisoliton solutions easy to construct.
• The dependent variables are usually tau-functions, with good properties.
• Natural for the Sato theory, which explains hierarchies of integrable equations (Jimbo and Miwa)
• Suitable for classification: the bilinear form strongly restricts the freedom of changing dependent variables.
