\section*{Summary} % '*' suppresses the numbering
The main goal of this lecture was to summarize the presentations for the semester. We begin with Gauss composition of binary quadratic forms as described in \cite{Seguin}.
\begin{definition}
A {\em binary quadratic form} $f(x,y)$ over a ring $R$ is a homogeneous polynomial of degree two in two variables. In other words, $f(x,y)$ is a binary quadratic form if and only if
$$f(x,y) = ax^2 + bxy + cy^2$$ % equation display
where $a,b,c \in R$.
\end{definition}
There is a natural action of $\GL_2(\mathbb{Z})$ on the space of binary quadratic forms over $\mathbb{Z}$...
