The GAMM Committee l'or Efficient Numerical l1ethods l'or Partial Differential Equations (GAMM FachausschuB "Effiziente Numerische Verf'ahren fiir Partielle Differentialgleichungen") organizes conferences and serninars on subjects concerning the algorit hmic treatment of partial differential equation problerns. The two flrst serninars "Efficient Solution of Elliptic Systems" 098S) and "Efficient Numerical Methods in Continuum Mechanics" (986) were followed by a third one, co-organized together with the GAMM Committee l'or Dlscre tizing Methods in Solid Mechanics and the special re search...
