Home base is #linearalgebra (esp #eigenvalues), computational #mechanics, #optimization. Work on numerical methods for #data science, formal verification of numerics, #plasma #physics for #fusion, etc. I run our Center for Applied Math, am assoc dean for #DEI in the college. Collect #fountainpens, read #scifi & #fantasy, #code in #julia (and C/C++, Fortran). Also #coffee, #tea, #books, more #books.

However, I never understood, why we were learning this.

I asked a question about #Mandelbulb #Jacobian #Eigenvalues because I got stuck and #SageMath wasn't helping by spewing thousands of lines of formulas that I struggled to persuade it to simplify.

$$K = \frac{\max_k{|\lambda_k|}}{\min_k{|\lambda_k|}}$$
where the $\lambda_k$ are the #Eigenvalues. That gives me a bit more of an intuition I suppose...
Now to try to get #maxima to calculate it for my particular functions of interest
