We study
the stability of
the zero equilibrium of
the following system of difference equations, which is a natural extension of an one-dimensional biologicalmodel:

The stability of those systems in
the special case when one of
the eigenvalues has absolute value equal to 1 and
the o
ther two eigenvalues have absolute value less than 1, using centre manifold
theory, is investigated.
