Identify template for lecture notes

Question

Very simple, but does anyone know which LaTeX template these lecture notes are done in?

Answer 1

This is quite an easy template to copy, you can start with something like this, and further tune things as you want:

\documentclass[20pt]{extarticle}
\usepackage[left=1in,right=1in]{geometry}

\begin{document}
\raggedright

\section{Markov Chains}

\begin{itemize}
\item The Markov property is common in probability
models because, by assumption, one supposes
that the important variables for the system being
modeled are all included in the state space.

\end{itemize}

\end{document}

Answer 2

Save this code as satz.sty and import into an amsart class. Code inspired and borrowed from Some Fundamental Theorems in Mathematics, which by the way is an excellent read.
