# Pearl-Verhulst Logistic Growth model
The classical logistic-growth model (Kot 2001) assumes that the growth of a population decreases with increasing population size and is given by the following equation,
$\frac{dN}{dt} = rN \times \left(1 - \frac{N}{K}\right)$ where $$N$$ is the number (density) of indviduals at ... | {} |
# Entering a black hole theoretically of course
Hey all this is my first post,
Everyone knows you can't enter a black hole because you'll be stretched/turned into noodles due to the immense change in gravity over small lengths. I was reading another thread on the physics forum and happened to come across an equation ... | {} |
# Isomorphism of symmetric groups.
True or false? Give reason.
$S_m\times S_n\simeq S_{m+n}$.
I know this is not true but I don't know how to prove it.

#### Abstract
We consider the estimation problem for the parameter $\vartheta_0$ of a stationary ARMA $(p, q)$ process, with independent and identically, but not necessary normally distributed errors. First we prov... | {} |

# Preface
This section (including following subsections) is devoted to analysis of linear differential equations with singular points. Its theory is due mainly to the German mathematicians Carl Gauss (1777--1855), Bernhard Riemann (1826--1866), Lazarus Fuchs (1833--1902), and Georg Frobenius (1849--1917). Gauss and Ri... | {} |
