     ABSTRACT

     A recursive, shape controlling triangulation method  is
     described.   The method is designed to produce a label-
     ing which implies reduced fill in the solution of (Fin-
     ite Element) equations assembled from such a triangula-
     tion and  allows  simple  implementation  of  a  nested
     disection  algorithm  for  irregular domains.  This ap-
     proach saves a substantial amount of time usually spent
     on discovering a suitable relabelling of the triangula-
     tion.  In addition, the matrix of the resulting  system
     is  them endowed with a recursive doubly bordered block
     diagonal form.  This allows us to develop  a  recursive
     parallel  bisection method for the solution of the sys-
     tem of equations.
