| | | | | In the last post, Geodesics of left invariant metrics on matrix Lie groups - Part 1,we have derived Arnold's equation - that is a half of the problem of finding geodesics on a Lie group endowed with left-invariant metric. Suppose $G$ is a Lie group, and $g(\xi,\eta)$ is a scalar product (i.e. | |

| | | | | I know it is a controversial opinion, but you might need to know where things are when running a simulation. As a bonus, it helps you in knowing what to draw on the screen. Of course, you can just use a position vector (x, y, z) where x, y and z are the coordinates of ... Continue reading Solving Kepler's Equation 5 Million Times a Second ? | |

| | | The logarithmic potential is a classical object of potential theory intimately connected with the two dimensional Laplacian. It appears also in free probability theory via the free entropy, and in partial differential equations e.g. Patlak-Keller-Segel models. This post concerns only it usage for the spectra of non Hermitian random matrices. Let \( {\mathcal{P}(\mathbb{C})} \) be the set of probability measures... | ||
