I was studying a Master's thesis on functional analysis and I was attracted by the novel-like heading used by the author for the chapters. 
How can I replicate it?
I was studying a Master's thesis on functional analysis and I was attracted by the novel-like heading used by the author for the chapters. 
How can I replicate it?
Here is an example of what can be done with titlesec (and xrfill + xcolor):
\documentclass{book}
\usepackage[svgnames]{xcolor}
\usepackage{titlesec}
\usepackage{xhfill}
\colorlet{rulecolor}{Gainsboro!40!Lavender}
\usepackage{lipsum}
\titleformat{\chapter}[display]
{\filcenter}{\mbox{}\xrfill[0.4ex]{3pt}[rulecolor]\textsc{\large\enspace\chaptername \thechapter}\enspace\xrfill[0.4ex]{3pt}[rulecolor]\mbox{}}{0.3ex} {{\color{rulecolor}\titlerule[1pt]}\vskip3ex\huge\bfseries}[\medskip{\color{rulecolor}\titlerule[1pt]}]
\begin{document}
\chapter{The General Structure of\\ von Neumann Algebras}
\lipsum[2]
\end{document
\chaptername \thechapter should probably become something like \chaptername~\thechapter.

Without any packages and the standard book class you can achieve this
as follows.
\documentclass{book}
\makeatletter
\def\thickhrulefill{\leavevmode \leaders \hrule height 1ex \hfill \kern \z@}
\def\@makechapterhead#1{%
%\vspace*{50\p@}%
\vspace*{10\p@}%
{\parindent \z@ \centering \reset@font
\thickhrulefill\quad
\scshape \@chapapp{} \thechapter
\quad \thickhrulefill
\par\nobreak
\vspace*{10\p@}%
\interlinepenalty\@M
\hrule
\vspace*{10\p@}%
\Huge \bfseries #1\par\nobreak
\par
\vspace*{10\p@}%
\hrule
%\vskip 40\p@
\vskip 100\p@
}}
\def\@makeschapterhead#1{%
%\vspace*{50\p@}%
\vspace*{10\p@}%
{\parindent \z@ \centering \reset@font
\thickhrulefill
\par\nobreak
\vspace*{10\p@}%
\interlinepenalty\@M
\hrule
\vspace*{10\p@}%
\Huge \bfseries #1\par\nobreak
\par
\vspace*{10\p@}%
\hrule
%\vskip 40\p@
\vskip 100\p@
}}
\begin{document}
\chapter{Introduction}
\end{document}
The code is take from here.
First of all, check if your school has a template (hopefully in LaTeX!) for theses. If not, make sure that you respect (as far as reasonable/really required, see below) their standard format.
If I had to create my own style, I'd start with the (very customizable) memoir class (standard, available with major TeX distributions, comes with extensive and readable documentation; also check out memdesign on CTAN, it talks about how/why to design books), and look if one of the many chapter styles is what you want (or is near enough so you can tweak it to taste), check Madsen's "Various chapter styles for the memoir class" large collection of examples.
Re: "Reasonably respect guidelines": Here (haven't checked lately, but it was so a few years back), theses had to be written double spaced, one-sided, and only in Spanish. The first part is just leftovers from typewriter days (my thesis was written with one), the second part is pure nonsense (I guided several theses where the interested parties were international organizations, with English as principal/only language). Our library was thrilled with single-spaced, two-sided theses (less shelf space!), the Powers That Be didn't complain (didn't notice? didn't care?). But do check beforehand, get your advisor's support for any straying from the narrow path.
memoirclass you can customized the chapter headings. See e.g. this PDF. The example on page 42 looks already quite similar. Try to adapt it and if you have any question, show us what you have with a MWE and for sure someone will help.You can have a look at our starter guide to familiarize yourself further with our format.
