Here is the github link uathesis where I am using to write up my dissertation with the newer class uathesis.

All I am doing is to replace my text body with that of the templates.

Here is the dissertation.tex file:

My bibliography.bib file of the project is a lengthy one and as soon as it is replaced with the empty one in the project, I am receiving a bunch of error messages as follows all related to the entries of the bibliography file:

Missing $ inserted.

Check that your $'s match around math expressions. If they do, then you've probably used a symbol in normal text that needs to be in math mode. Symbols such as subscripts ( _ ), integrals ( \int ), Greek letters ( \alpha, \beta, \delta ), and modifiers (\vec{x}, \tilde{x} ) must be written in math mode. See the full list here.If you intended to use mathematics mode, then use $ … $ for 'inline math mode', $$ … $$ for 'display math mode' or alternatively \begin{math} … \end{math}.

Best Answer

Bases on your given link in the question and the bib file you gave in your last question I was able to create a MWE for your case here. See the code later.

The error message you got

Package natbib Error: Bibliography not compatible with author-year citations.

(natbib)                Press <return> to continue in numerical citation style.

Indicates, that you have missed to add options numbers to natbib to get a numbered bibliography ([1]) and not a bibliography following author-year citations ([CMQ2016]).

To get a simple MWE I just deleted the\included files and simply copied a small code for indroduction (you gave in the last question, it fit's better to your given bib file) into that MWE. So I got the resulting MWE

\RequirePackage{filecontents}
