Dear List Members,

I have a problem with bibliography for org mode.

1. Here is my org mode file:

* Monoidal categories

  These notes are based on the book [[cite:JohnsonYau2021][2-dimensional categories (OUP, 2021)]].
  
  1. [[label:][monoidal category definition]]
     A /monoidal category/ is $\moncat{\Bb{A}}{\otimes}{\alpha}{\lambda}{\rho}$, where:

     + $\Arr{\otimes}{\Bb{A} \times \Bb{A}}{\Bb{A}}$ is a bifunctor, called the
       /monoidal product/,

     + an object $\unit$ of $\Bb{A}$, called the /monoidal unit/,

     + three natural isomorphisms --- the /left unit isomorphism/ $\langle\Arr{\lambda_{X}}{\unit \otimes X}{X}: X \in \Bb{A}_0 \rangle$, the /right unit isomorphism/ $\langle\Arr{\rho_{X}}{X \otimes \unit}{X}: X \in \Bb{A}_0 \rangle$ and the /associativity isomorphism/ $\langle\Arr{\alpha_{X, Y, Z}}{(X \otimes Y) \otimes Z}{X \otimes (Y \otimes Z)}: X, Y, Z \in \Bb{A}_0 \rangle$,

     + these are subject to:

\section{Monoidal categories}
\label{sec:org942f09d}

These notes are based on the book \cite[2-dimensional categories (OUP, 2021)]{JohnsonYau2021}.

\begin{enumerate}
\item \label{}
A \emph{monoidal category} is \(\moncat{\Bb{A}}{\otimes}{\alpha}{\lambda}{\rho}\), where:

\begin{itemize}
\item \(\Arr{\otimes}{\Bb{A} \times \Bb{A}}{\Bb{A}}\) is a bifunctor, called the
\emph{monoidal product},

\item an object \(\unit\) of \(\Bb{A}\), called the \emph{monoidal unit},

\item three natural isomorphisms --- the \emph{left unit isomorphism} \(\langle\Arr{\lambda_{X}}{\unit \otimes X}{X}: X \in \Bb{A}_0 \rangle\), the \emph{right unit isomorphism} \(\langle\Arr{\rho_{X}}{X \otimes \unit}{X}: X \in \Bb{A}_0 \rangle\) and the \emph{associativity isomorphism} \(\langle\Arr{\alpha_{X, Y, Z}}{(X \otimes Y) \otimes Z}{X \otimes (Y \otimes Z)}: X, Y, Z \in \Bb{A}_0 \rangle\),

\item these are subject to:

\[
       \label{eq:pentagon-axiom}
       \xymatrixcolsep{5.4em}
       \xymatrixrowsep{3em}
       \xymatrix{
       {((X \otimes Y) \otimes Z) \otimes W} \ar[d]_-{\alpha_{X \otimes Y, Z, W}}
       \ar[rr]^-{\alpha_{X, Y, Z}\otimes\id{W}} & &
       {(X \otimes (Y \otimes Z)) \otimes W} \ar[d]^-{\alpha_{X, Y \otimes Z, W}} \\
       {(X \otimes Y) \otimes (Z \otimes W)} \ar[r]_-{\alpha_{X, Y, Z \otimes W}} &
       {X \otimes (Y \otimes (Z \otimes W))} &
       {X \otimes ((Y \otimes Z) \otimes W)} \ar[l]^-{\id{X} \otimes \alpha_{Y, Z, W}}
       }
       \]

and

\[
       \label{eq:unity-axiom}
       \xymatrixcolsep{5.4em}
       \xymatrixrowsep{3em}
       \xymatrix{

4. The line from my /emacs file:

(require 'org-ref)
(require 'ox-bibtex-chinese)
(require 'reftex)

(setq org-latex-pdf-process
      '("pdflatex -interaction nonstopmode %f"
        "biber %b"
        "pdflatex -interaction nonstopmode %f"
        "pdflatex -interaction nonstopmode %f"))

I do not have ox-bibtex from melpa, this is what I have!

5. The exported .pdf file:

[-- Attachment #9: Type: text/plain, Size: 542 bytes --]


My problems are:

1. the citation is not listed

2. the bibliography resource files are reproduced

3. another problem: my locale is "bn-IN" and there are file names which
contain bengali characters; whenever I try to have a link
[[file:/filename with bengali names/][description]] this is not properly
recognised in the exported pdf file but in the org file it is recognised
and clicks properly.

I would be thankful if some one can provide me clues to the solution of
these issues.



With my regards and all the very best wishes,
