#+TITLE: Algebraic Topology I - README
#+AUTHOR: Han-Miru Kim
#+PROPERTY: header-args :tangle ./header.tex
* About
This file contains general information about the lecture notes aswell as the configuration for my Algebraic Topology notes.
It is an Emacs Org Mode file which is edited and then /tangled/ with the ~header.tex~ file, which I do not touch manually.
The benefit of this is that comments, which would have been written in plaintext inside ~header.tex~ can now be written using Org Mode Formatting, allowing for literate configuration.
For example, I can use headings, use formatted text, insert tables, source code blocks or even images, which would not be possible in LaTeX comments.
I structure my notes as follows:
Instead of a ~main.tex~ file, I have a ~main.org~ file which I then export to latex via ~M-x org-export-dispatch l o~.
Since I have just started using Emacs, my configuration does not quite allow me to take notes in real-time.
This means I still take my notes in Vim by writing ~.tex~ files and putting them in the ~./files~ directory, from where they will be sourced and can be compiled using my existing vim-tex setup.
** How to use
After changing the configuration, place the point at the top of this document (~g g~ in evil-normal mode) and do ~C-c C-c~ to refresh. Then execute ~M-x org-babel-tangle~, which will update ~header.tex~.
It should output ~Tangled n code blocks from README.org~
To use source code blocks without having them exported to ~header.tex~, use the ~:tangle no~ option.
** TODO
- I plan on trying out an Emacs-only solution which will let me export this document in ~.html~ format and upload it on my webpage.
- As of now, I use different configuration files for every lecture. This means that there is alot of code redundancy as the configuration only differs by about 5% (if at all) between different lecture notes.
But since the README.org files are only a couple kilobytes in size each, I should be fine.

The last three lines swap the commands ~\phi~ and ~\varphi~.

* Environments
** Default Environemnts
Changing the behaviour of the ~enumerate~ environment to use letters over roman numerals.
#+BEGIN_SRC latex
\renewcommand{\labelenumi}{(\alph{enumi})}
#+END_SRC
** Theorem
Define the environments using the ~amsthm~ package.
They are easy to set up and respect the section numbering, but I prefer the fancy coloured boxes using ~mdframed~.
#+BEGIN_SRC latex
%\newtheorem{thm}{Theorem}[section]
%\newtheorem{cor}{Corollary}[thm]
%\newtheorem{lem}[thm]{Lemma}
%\newtheorem{prop}{Proposition}[thm]
%\theoremstyle{definition}
%\newtheorem{dfn}[thm]{Definition}

%\newtheorem{note}[thm]{Note}
%\newtheorem{ex}[thm]{Example}
#+END_SRC
** Math boxes
From https://tex.stackexchange.com/questions/20575/attractive-boxed-equations:
Requires the the ~empheq~ and ~tcolorbox~ packages.
Makes the cool blue equation boxes.
#+BEGIN_SRC latex
\newtcbox{\bluebase}[1][]{%
nobeforeafter, math upper, tcbox raise base,
enhanced, colframe=black,
colback=blue!20, boxrule=0.5pt,
sharp corners,
#1
}
#+END_SRC
You can then write the equations as follows
#+BEGIN_SRC latex :tangle no
\begin{empheq}[box=\bluebase]{align*}
\nabla \cdot E = \frac{\rho}{\epsilon_0}
\end{empheq}
#+END_SRC
** Fancy Boxes
*** Setup
Taken from this [texblog post](https://texblog.org/2015/09/30/fancy-boxes-for-theorem-lemma-and-proof-with-mdframed/)
Setup numbering system and define a function that creates environment.
~\newenvironment~ takes one optional and three necessary arguments.
- The environment name (that which is put inside ~\begin{###}~)
- The Title name which is printed on the page
- The colour of the box. I use colors in the format ~blue!50!green!50~ etc.

\section{Preparation}
This section consists of some work done before the lectures started. It won't be included in any exports.
I wanted to try out using Emacs Org Mode to take notes (instead of neovim + vimtex I have been using for the past year).
After trying out the environments from the amsthm package and comparing them to the mdframed boxes, I found that while the theorem numbering is nice and easy to setup, I miss the colorful boxes that make searching for definitions much easier.
I will try to get the theorem numbering to work and make abstract the environment creation to reduce code redundancy.
\subsection{Motivation}
Being able to measure the rate at which things change -- that is differentiating them -- is such a crucial part in many applications of mathematics.
The way we treated differentiability in Analysis I \& II however restricted us to Euclidean spaces.
But sadly, many models of the real world are not defined on nice subspaces of a Euclidean space.
Our first aim is to generalize the notion of a derivative to let us differentiate functions from ``nice'' topological spaces so called \emph{smooth manifolds}.
These topological spaces should be general enough to apply to many situations but still strong enough to carry over some of our tools from Analysis.
\begin{dfn}[]
A topological space is called \textbf{metrisable}, if there exists a metric on the space that induces its topology.
\end{dfn}
Alternatively, one can call a topological space metrisable, if it is homeomorphic to a metric space.
\begin{ex}[]
Find interesting examples of non-metrisable spaces that may come up in other fields.
\end{ex}
\begin{itemize}
\item A simple example (and a source of many other counter-examples) is the Sierpinsky-space
\begin{align*}
X = \{a,b,c\}, \quad \tau = \{\emptyset, \{a\},X\}
\end{align*}
As $\{a\}$ is an open set, we know that $d(a,b), d(a,c) >0$.
But the open ball $B(b, \frac{d(a,b)}{2})$ does not contain $a$ and should be open.
But the only open set that does not contain $a$ is $\emptyset$, which doesn't contain $b$.
%\item The Sorgenfrey-line $\R_l$, has the topology induced by half-open intervals of the form $[a,b)$.
\end{itemize}
\begin{dfn}[]
A metrisable topological space is called \textbf{separable}, if there exists a countable dense subset.
\end{dfn}
\begin{dfn}[]
A topological space is called \textbf{locally Euclidean} of \textbf{dimension} $m$ if every point has a neighborhood that is homeomorphic to $\R^{m}$.
\end{dfn}
