Hi Curves Fans,
Elsewhere I have not seen a bi-rational shear transformation, which obtains
the Jacobi Quartic from a plane cubic. Here's another video:
...showing a continuous transformation which takes one line + one parabola
into two parabolas. As a consequence, another addition rule exists aside
from the one presented in "Jacobi Quartic Curves Revisited".
Also, I see that Michael Naehrig keeps a list of songs (
https://cryptosith.org/music/index.shtml ) incidentally related to
cryptography. I can't say that I understand any of the entries on this
list, but would like to contribute another anyways:
"A Lotus on Irish Streams" -- Mahavishnu Orchestra, Inner Mounting Flame,
To be clear, this is a joke about Hamiltonian Flows.
PS. Errata: previous message (
