Though differential algebra historically grew out from the classical
   analysis applied to algebraic differential equations, it has become a
   pure algebraic tool of their investigating and solving.  Combined with 
   computer algebra, it provides a researcher with a powerful tool 
   applicable to those differential equations which are polynomials in 
   unknown functions and their derivatives over a coefficient field which 
   is stable under differentiation.

   The session aims are to provide a forum for discussing differential 
   algebra methods, algorithms and software packages applied to ordinary 
   and partial differential equations.
