# Talk:Neimark-Sacker bifurcation

This is an excellent article. I have only the following remarks:

Text just below Figure 1 and Figure 2: a fixed point (instead of "an fixed point")

Two lines further: resulting in a stable ...

One line further: When it happens...

The text contains several times the name "Poincare". Is it possible to give Poincar'e the right accent? There should be a solution for that...

Two lines above the section on Arnold tongues: Note that in some books...

In the text on Arnold tongues: there exists only a finite number of...

In the text on the Multi-dimensional case: such that (instead of "suach that")

In the text on the First Lyapunov Coefficient: Whether a Neimark-Sacker...

Same section: c(0) is not necessarily real. In the formula for c(0) no real part should be taken.

Section on "Torus bifurcation": Then a unique two-dimensional...
