Definition

Let us have a set of points, {a0,a1,,aN}Rn[Note 1], we say they are geometrically independent if[1]:

  • {t0,t1,,tN}R[(Ni=1ti=0Ni=1tiai=0)(t0=t1==tN=0)]

The reader should note that this is very similar to linear independence; in fact, {a0,,aN} is geometrically independent iff the set {a1a0,,aNa0} is linearly independent
