When ignoring the parameter-dependency, the takens normal form can be derived formally by analyzing the resonant terms. If we want to preserve the parameter-dependency, how can the simplest form...

I have a dynamical system restricted to it's (1d-) Center Manifold. All coefficients of the 'pure' variable up to a certain order are zero. There are not enough parameters to fully unfold the...

If we have a dynamical system that is not in general position (see Shilnikov, 2nd book, p. 546) that means the matrix: [ \frac{\partial G}{\partial \epsilon_1} & \ldots & \frac{\partial...

If you have a dynamical system with zero eigenvalues in the linear part, one common method to restrict it to the center manifold is to transform it such that the linear terms are in Jordan normal...

Given a 2D-vector field with a non-hyperbolic fixed point, I would like to have an overview of all possible bifurcations and their normal forms and versal unfoldings, including for bifurcations...

I want to plot a curve in R^3 that is defined implicitly by the two constraints f_1(x_1,x_2,x_3)=0 and f_2(x_1,x_2,x_3)=0.

I have a two dimensional, non-linear vector field [f_1(x_1,x_2); f_2(x_1,x_2)] with a fixed point at the origin. Is there a generally applicable, easy to understand (for engineers) method for...

The quadratic term of a Taylor expansion of a multivariate scalar valued function can be expressed in terms of the Hessian. Is there a similar form for vector valued functions, in the sense that...
