Here's a very simple way to do it.

\documentclass{article}
\usepackage{amsmath}
\begin{document}
\begin{gather*}
\boxed{\text{difficult problem for an individual operator}} \\
\downarrow \\
\boxed{\text{simpler problem for a \(C^*\)-algebra}} \\
\downarrow \\
\boxed{\text{result for the \(C^*\)-algebra}} \\
\downarrow \\
\boxed{\text{desired result for the individual operator}}
\end{gather*}
\end{document}

However, if the diagram was more complicated other tools (like TikZ) would be more appropriate.

You can do this with Tikz:

\documentclass[border=1cm]{standalone}

\usepackage{tikz}
\usetikzlibrary{shapes.misc,positioning}

\begin{document}
    
    \begin{tikzpicture}[node distance=1cm,outer sep=0.5cm]
        

    \node[rectangle,,draw=black](a) at (0,0) {difficult problem for an individual operator};
    \node[rectangle,draw=black,below=of a] (b) {simpler problem for a C*-algebra};
    \node[rectangle,draw=black,below=of b] (c) {result for the C*-algebra};
    \node[rectangle,draw=black,below=of c] (d) {desired result for the operator};
    
    \draw [->] (a) edge (b) (b) edge (c) (c) edge (d);

    
        \end{tikzpicture}
    
\end{document}
