Hopf bifurcation how to prove

291 Views Asked by At

I have this system of differential equations:

\begin{equation} \frac{dx}{dt}=1-(b+1)x+x^2 y\\ \frac{dy}{dt}=bx-x^2 y \end{equation}

I now that we will have a bifurcation when $b$ grows and passes $2$ and we know that the stationary point is $(1,b)$.

I know that we need to change the variables in our systems to our new variables $u = x - 1$ and $v = y - b$

I understand that it will be three conditions:

non-hyperbolicity condition: conjugate pair of imaginary eigenvalues) transversality condition: the eigenvalues cross the imaginary axis with non-zero speed genericity condition

Can you help med attack this problem?
