When citing authors, the soul package is useful. It provides small caps with additional spacing. Use it as:

\so{Author Name}

Include the package babel and babelbib in the preamble:

\usepackage{babel}
\usepackage{babelbib}

Use the following command to produce the bibliography:

\bibliographystyle{babalpha}
\bibliography{bibliography_file}

Setup hyperref to include correct author name and opening mode for PDF files:

\hypersetup{
  pdfauthor={Author Name <name@domain.tld>}, pdfstartview={FitV}

Some often used operators and functions:

\providecommand{\abs}[1]{\lvert#1\rvert}
\providecommand{\norm}[1]{\lVert#1\rVert}
 
\DeclareMathOperator*{\argmax}{arg\,max}
