Optimal realisations
Seminar Room 1, Newton Institute
For a metric $(X,d)$ a weighted graph $G= (V, E, w)$ is called a realization of $d$ if (i) $X \subseteq V$ (ii) $d_g(x,y) = d(x,y)$ for all $x, y \in X$.
A realization is called {\em optimal} if the sum $\sum_{xy \in E} w(xy)$ is minimal among all the realizations. ... | {"url":"http://www.newton.ac.uk/programmes/PLG/seminars/2007121810401.html","timestamp":"2014-04-21T14:48:05Z","content_type":null,"content_length":"6459","record_id":"<urn:uuid:71329eb6-aef9-4d87-81df-543c97dcd1ba>","cc-path":"CC-MAIN-2014-15/segments/1397609540626.47/warc/CC-MAIN-20140416005220-00393-ip-10-147-4-33.e... |

derivation of the Christoffel symbol
Did you obtain a result like
[tex]g_{\rho\sigma,\mu}=\Gamma^\lambda_{\mu\rho}g_{\lambda\sigma}+\Gamma^\la mbda_{\mu\sigma}g_{\rho\lambda}[/tex]

Counting generates from the programmer’s successor function ++ and the number one. (You might argue that to get out to infinity requires also repetition. Well every category comes with composition by

Y-intercepts of this function

Y-intercepts of this function
$f(x)=7(x-4)^{\frac{3}{4}} - 3(x-4)^{\frac{7}{4}}$
Do the y-intercepts exist for this function? According to wolframalpha they do, but I don't see how that's possible.

Ermentrout-Kopell canonical model

The Ermentrout-Kopell canonical model is better known as the "theta model" and is a simple one-dimensional model for the spiking of a neuron. It is closely related to the quadratic integrate and fire

The equations of motion for a free rigid body whose center of mass is at the origin are given by the following Euler equations (see [MR99]).
