Higher covariant derivatives and the exterior derivative

Let me start with the following tl;dr version of my question What is a higher-order derivative, in general? How does it relate to the exterior derivative and to differential forms? Suppose we have a bundle and a section $E \overset{\sigma}{\underset{\pi}{\leftrightarrows}} M$. Assume we have a connection on $E$. (One of the links assumes we also […]

Find $P(X

I am a little confused with finding $P(X<3)$ and $E(X)$. Here, A,B,C are Poisson random variables with parameters 2.6,3, and 3.4, respectively. Let X be the number of errors typed in a manuscript. Each of three typists A,B,C are equally likely to type the manuscript with error rates given. For the $E(X)=\frac{1}{3}(2.6+3.4+3)=3$ but I am […]

matrix of special form

I have come across this matrix \begin{equation*} A_{m,n} = \begin{pmatrix} a_{1} & a_{2} & a_{3} \cdots & a_{n} \\ a_{2} & a_{2} & a_{3} \cdots & a_{n} \\ a_{3} & a_{3} &a_{3}\cdots & a_{n}\\ \vdots & \vdots & \ddots & \vdots \\ a_{n} & a_{n} & \cdots & a_{n} \end{pmatrix} \end{equation*} where, also, $a_{1} \geq […]

Show that $K_2(F)$ is a direct summand of $K_2F(t)$

I have a question regarding Example 6.1.2 (page 252) from the book “The K-Book” by Charles Weibel. Here is the statement: Example 6.1.2: Let $F(t)$ be a rational function field in one variable $t$ over $F$. Then $K_2(F)$ is a direct summand of $K_2F(t)$. $\text{ }$ I find it quite difficult to understand the argument, […]

Computation of balance equation example in Markov model

I am studying some examples of balance equations for Markov models. I am presented with the following example: $$\mathcal{P} = \begin{bmatrix} 0.2 & 0.3 & 0.5 \\ 0.1 & 0 & 0.9 \\ 0.55 & 0 & 0.45 \end{bmatrix}$$ [dropping the $i$ subscript by writing $\pi_j$ for $\pi_{ij}.]$ The balance equations are $$\begin{align} &\pi_1 = […]
