 Associative algebras have proven themselves remarkably useful throughout
 mathematics. There's no lack of natural and interesting examples coming from a
 diverse spectrum of different fields: topology, number theory, analysis, you

+\chapter*{About These Notes}
 
-Throughout this notes we'll follow the following guiding principles:
+This is my undergraduate dissertation, produced in 2022 under the supervision
+of professor Iryna Kashuba of the department of mathematics of the Institute of
+Mathematics and Statistics of the Univety of São Paulo (IME-USP), Brazil.
 
-\begin{enumerate}
-  \item Lengthy proves are favored as opposed to collections of smaller lemmas.
-    This is a deliberate effort to emphasize the relevant results.
+Throughout this notes we'll follow some guiding principles. First, lengthy
+proves are favored as opposed to collections of smaller lemmas. This is a
+deliberate effort to emphasize the relevant results. Secondly, and this is more
+important, we are primarily interested in the broad strokes of the theory
+highlighted in the following chapters. The topic of the dissertation at hand,
+the resentation theory of Lie algebras, is a profoundly technical. In
+particular, certain proofs can sometimes feel like an unmotivated pile of
+technical arguments. Instead, we prefer to focus on the intuition behind the
+relevant results.
 
-  \item We prefer, whenever possible, to outsource proofs. This is because I
-    don't fancy reinventing the wheel: I'll write down proofs in here
-    \emph{only} when I fell like I have something to add to the proofs provided
-    by other materials. Otherwise we refer the reader to the proofs in other
-    books or articles -- which will likely be indicated just after the
-    statement of the theorem.
-\end{enumerate}
+Hence some results are left unproved. Nevertheless, we include numerous
+references throughout the text to other materials where the reader can find
+complete proofs. We'll assume basic knowledge of abstract algebra. In
+particular, we assume that the reader is familiarized with multilinear algebra
+and the theory of modules over a ring. Understanding some examples in the
+introductory chapter requires basic knowlage of differential and algebraic
+geometry, as well as rings of differential operators, but this examples are not
+necessary to the comprehension of the following chapters. Additional topics
+will be covered in the notes as needed.
 
-We'll assume basic knowledge of abstract algebra and module theory. Additional
-topics will be covered when needed.

+I would like to thank my parents for their love and support. I would specially
+like to thank professor Kashuba and Eduardo Monteiro Mendonça for their
+support. Their guidence over the past two years has profoundly shaped my
+passion for mathematics, and I could not have gotten to where I am now without
+their help. I suppose I should also thank them for enduring my chaotic
+digressions on the relationship between representation theory and geometry.
+Finally, I would like to thank my dear friend Lucas Dias Leme Schiezari for
+somehow convincing me to apply for a bachalors degree in pure mathematics. May
+he rest in peace.
