We consider ordinary differential equations of the form
(0.1)with a diagonal matrix D(σ) = diag[1,…,σ,…,1] which differs from the unit matrix by an entry σ in the row (and column) ic. Here τ ε ℝ and σ>0 are considered as bifurcation parameters. Note that stationary solutions of (0.1)

and are thus independent of σ.
