           Rational curves play an important role in the field of Computer 
          Aided Geometric Design. They arise in practical applications as 
          computer graphics, geometric modelling or manipulation of offset
          varieties.
            Recently, symbolic methods in Computer Algebra are been applied
          successefully to rational curves. In this session the most 
          relevant recent advances in the field of parametric curves and 
          their applications to Computer Aided Geometric Design will be 
          reported.
