DiffAlgField -- the class of all vector fields

Functions and methods returning an object of class DiffAlgField :

• DiffAlgField | DiffAlgField -- Lie bracket
• newField(ZZ,ZZ,String), see newField -- constructor of a vector field
• newField(String) -- constructor of a vector field
• radial(ZZ), see radial -- defines the radial vector field

Methods that use an object of class DiffAlgField :

• DiffAlgField _ DiffAlgForm -- contraction of a differential form with respect to a vector field
• DiffAlgForm _ DiffAlgField, see DiffAlgField _ DiffAlgForm -- contraction of a differential form with respect to a vector field

For the programmer

The object DiffAlgField is a type, with ancestor classes DiffAlgElement < HashTable < Thing.
