Degree of symmetry of Riemannian manifolds www2.math.upenn.edu/~wziller/mat...

I disabled the view "title" (filename) option and write the "title" as a H1 header.

The new file template I use automatically adds the "title" in the three places: "title" property, "aliases" property and the H1 header.

Cauchy problem for inviscid Burgers' equation is not "solvable" (globally) for many initial conditions...but we can depict the graph of the function that "could have been the solution"... (and the characteristic surface of course)

Exactly! I am using it for almost everything I can think of now. Example: while trying to give bounds for Fourier coefficients of a 1-periodic function on R, we realise integration by parts gives non-trivial bounds. Here, red is the original naive integral, we only care about integer values...

A sympy script in #obsidianmd. Powers of Arnold cat map matrix gives you FIbonacci coefficients and thus they grow exponentially...

Red: preimage of unit disk under a complex polynomial, or |p(z)|< 1
Violet, black: Curves defined by real and complex parts of p = 0 resp.
