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: where md5=8f955869afeb23a2b2f473cf32bec74b" title="Click to view the MathML source">a₁$a_1$, md5=7c566ad9ed0e6d26164c2e0a702057be" title="Click to view the MathML source">a₂$a_2$, md5=a4799aeb699a30fa775abd016d434320" title="Click to view the MathML source">a₃$a_3$, md5=99ff3bf90a5e37197502932804bd62a3" title="Click to view the MathML source">b₁$b_1$, md5=2749d696ff017c52f12d39dc437a1b16" title="Click to view the MathML source">b₂$b_2$, md5=867a949030655d4ff4c90881ffa2a8f9" title="Click to view the MathML source">b₃$b_3$ are real constants and the initial values conditions md5=b99ce840cf43effad7b2681a256d557c" title="Click to view the MathML source">x₀$x_0$, md5=6ac2315f925119f1818bc84ee2690c4a" title="Click to view the MathML source">y₀$y_0$ and md5=c776f9d83bb80730f40d6737ab7bd605" title="Click to view the MathML source">z₀$z_0$ are real numbers. The stability of those systems in the special case when one of the eigenvalues has absolute value equal to 1 and the other two eigenvalues have absolute value less than 1, using centre manifold theory, is investigated.
