# Show that a group of order $p^2q^2$ is solvable
I am trying to prove that a group of order $p^2q^2$ where $p$ and $q$ are primes is solvable, without using Burnside's theorem. Here's what I have for the moment:
• If $p = q$, then $G$ is a $p$-group and therefore it is solvable.

Perhaps the most fundamental differential operator on Euclidean space ${{\bf R}^d}$ is the Laplacian
$\displaystyle \Delta := \sum_{j=1}^d \frac{\partial^2}{\partial x_j^2}.$
The Laplacian is a linear translation-invariant operator, and as such is necess... |
# Adjunction integral for Gysin map?
Let $f : X \to Y$ be a map between compact, orientable, smooth manifolds.
Then the Gysin map is defined by requiring that $\int_X f_! \alpha \wedge \beta = \int_Y \alpha \wedge f^*(\beta)$, for forms of suitable dimension.
This looks very much like an adjunction, if the integrati... |
# How do you evaluate cos(arcsin (1/4))?
Sep 10, 2015
$\frac{\sqrt{15}}{4} \approx 0.968$
#### Explanation:
By the fact that ${\cos}^{2} \left(\theta\right) + {\sin}^{2} \left(\theta\right) = 1$ for all $\theta$, when we know the value of $\sin \left(\theta\right)$, there are two possible corresponding values for $... |

# Sequence and Series
A set of numbers arranged in a definite order according to some rules is called a sequence or progression. It means that all consecutive terms must be related by some common rule or property.
Example: 1, 2, 3, 4, 5… is a sequence of consecutive natural numbers.
Similarly, 2, 4, 6, 8, 10…. i... |
# Projection of a measurable cylinder of the product $\sigma$-algebra
Take some set $A \subset \mathbb{R}$ such that $A \times \mathbb{R}$ is measurable in $\mathrm{B}(\mathbb{R}) \times \mathrm{B}(\mathbb{R})$, the product $\sigma$-algebra of the borel $\sigma$-algebra of $\mathbb{R}$ by itself (which is also $\mathr... |

### Information theory 2: source coding
6.9k words, including equations (~36min)
In the previous post, we saw the basic information theory model:
If we have no noise in the channel, we don't need channel coding. Therefore the above model simplifies to

# Time Value of Money
The internal rate of return (IRR) is simply the rate r that equates the future value of money to the present value. Despite being a foundational tool in financial analysis, the economic interpretation of this value is highly contested.
Before getting into the interpretation of IRR, lets establis... |
