OldPolyhedra :: dim(Fan)

dim(Fan) -- computes the dimension of a fan

Synopsis

Description

Returns the dimension of a fan. This is the maximal dimension of all cones of the fan.

i1 : F = hirzebruch 3

o1 = {ambient dimension => 2         }
      number of generating cones => 4
      number of rays => 4
      top dimension of the cones => 2
