Hello MHb,
Decide one parameter producing for line l through the points $$P=(1,1,2)$$ and $$Q=(2,-3,5)$$
This is a exempel from my book, I understand how they got the first line but not the second, (I hope that it don't mather it's on Swedish)

Hey Petrus,

Actually, it would be helpful if you translated the text in Swedish to English. Most of our members do not speak or read Swedish, and while mathematics is universal, the explanatory statements are meant to supplement the mathematical expressions, that is, to explain the reasoning behind them. So, in an effort to provide the most meaningful post to our members, you should translate everything into English.

While it may be easier for you not to translate, it then requires more effort on the part of those trying to help, and it should be the other way around. (Wink)

##\textbf{Exercise 10}:## I came across the following solution online: Questions: 1. When the author states in "that ring (not sure if he is referring to ##R## or ##R/\mathfrak{p}##, but I am guessing the later) ##x_n x_{n+1}=0## for all odd $n$ and ##x_{n+1}## is invertible, so that ##x_n=0##" 2. How does ##x_nx_{n+1}=0## implies that ##x_{n+1}## is invertible and ##x_n=0##. I mean if the quotient ring ##R/\mathfrak{p}## is an integral domain, and ##x_{n+1}## is invertible then...
The following are taken from the two sources, 1) from this online page and the book An Introduction to Module Theory by: Ibrahim Assem, Flavio U. Coelho. In the Abelian Categories chapter in the module theory text on page 157, right after presenting IV.2.21 Definition, the authors states "Image and coimage may or may not exist, but if they do, then they are unique up to isomorphism (because so are kernels and cokernels). Also in the reference url page above, the authors present two...
When decomposing a representation ##\rho## of a finite group ##G## into irreducible representations, we can find the number of times the representation contains a particular irrep ##\rho_0## through the character inner product $$ \langle \chi, \chi_0\rangle = \frac{1}{|G|} \sum_{g\in G} \chi(g) \chi_0(g)^*$$ where ##\chi## and ##\chi_0## are the characters of ##\rho## and ##\rho_0##, respectively. Since all group elements in the same conjugacy class have the same characters, this may be...
