### von Neumann stability analysis for spatial variable flux

Can we use the von Neumann stability analysis to investigate the stability of the discrete form of the following problem? $$u_t+\frac{\partial(x^2u)}{\partial x}=S(u,x)\ .$$ Please give some hint ...

### What does it mean for a finite difference scheme to be $L^1$-stable?

I am trying to answer a question about a finite difference scheme. I need to show that the method is stable in the L1-norm. I can't find a single definition of what that means, so does anyone have a ...

### Step size and stability of Euler forward method

I'm trying to calculate the maximum step size that provides stability for the following nonlinear IVP using the Euler forward method: $u'(t) = -200tu(t)^2,\qquad u_0 = 1, \qquad t\in [0,3]$, with ...

### Locally evaluate nonlinear dynamic system's stability using eigenvalues

I'm working with Computational Neuroscience. I have a large Synaptic Matrix (x axis: presynaptic NeuronID, y axis: postsynaptic NeuronID) in a Modular network. This matrix is close to a random one and ...
