Reference request: a differential equation in elementary geometry
If I map each circle of the torus stereographically to the line, then by your P.S. the equation becomes the equation for a straight line through the origin. |

A mysterious Heisenberg algebra identity from Sylvester, 1867
Very interesting! Graves essentially had the form of the star product. |

Calogero-Moser system: relationship between dual variables and the KKS construction
Yes, it appears in: Alexander G Abanov et al 2009 J. Phys. A: Math. Theor. 42 135201 (for the case of periodic boundary conditions) and Michael Stone et al 2008 J. Phys. A: Math. Theor. 41 275401. |

A heat kernel for Schrödinger operator with low-order terms
Shouldn't I be able to simplify the exponentials in terms of the shifted variables $\tilde x=x+b/2a$, $\tilde y=y+b/2a$? That is the origin of the $\exp(b^2t/4a)$, which reflects the shift of the quadratic potential. The terms you have don't seem to simplify nicely, however. |

Eigenvalues of random Hamiltonian matrices
Do I understand correctly that both real and imaginary axes have a $\sqrt{n}$ density of eigenvalues, but there is only repulsion around the imaginary axis? |
