To the best of my limited understanding, a virtual knot diagram may be thought of as the projection of an embedding of $\mathbb{S}^1$ in a 2-manifold with genus onto $\mathbb{R}^2$. That is to say it is an extension of the notion of a classical knot diagram to two dimens... | {} |
# Simple non-linear regression problem
I'm trying to model a simple use case: predicting the price of a car based on its mileage, with RStudio. I know it's a really naive model, just one variable, but it's for comprehension purposes.
My first attempt was to to use the lm function:
predictions <- lm(price~mileage, da... | {} |

Here the code for the diffusion equation. We took the Vibrating String code and modified it to show the diffusion phenomenon. The equation used is the well-known diffusion equation also the Heat Equation without source : \displaystyle f_t=\mu f_{xx} The resolution is the same that the vibrating string, ... | {} |

# Remarks on a class of kinetic models of granular media: Asymptotics and entropy bounds
• We obtain new a priori estimates for spatially inhomogeneous solutions of a kinetic equation for granular media, as first proposed in [3] and, more recently, studied in [1]. In particular, we s... | {} |

Why does $1+2+3+\dots = {-1\over 12}$?
Fermat's Dream by Kato et al. gives the following:
1. $\zeta(s)=\sum\limits_{n=1}^{\infty}\frac{1}{n^s}$ (the standard Zeta function) provided the sum converges.
2. $\zeta(0)=-1/2$
Thus, $1+1+1+...=-1/2$ ? How can this... | {} |
